Quick Start

tabulate is a header-only library. Just add include/ to your include_directories and you should be good to go. A single header file version is also available in single_include/.

NOTE Tabulate supports >=C++11. The rest of this README, however, assumes C++17 support.

Create a Table object and call Table.add_rows to add rows to your table.

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {

  Table universal_constants;

  universal_constants.add_row({"Quantity", "Value"});
  universal_constants.add_row({"Characteristic impedance of vacuum", "376.730 313 461... Ω"});
  universal_constants.add_row({"Electric constant (permittivity of free space)", "8.854 187 817... × 10⁻¹²F·m⁻¹"});
  universal_constants.add_row({"Magnetic constant (permeability of free space)", "4π × 10⁻⁷ N·A⁻² = 1.2566 370 614... × 10⁻⁶ N·A⁻²"});
  universal_constants.add_row({"Gravitational constant (Newtonian constant of gravitation)", "6.6742(10) × 10⁻¹¹m³·kg⁻¹·s⁻²"});
  universal_constants.add_row({"Planck's constant", "6.626 0693(11) × 10⁻³⁴ J·s"});
  universal_constants.add_row({"Dirac's constant", "1.054 571 68(18) × 10⁻³⁴ J·s"});
  universal_constants.add_row({"Speed of light in vacuum", "299 792 458 m·s⁻¹"});

You can format this table using Table.format() which returns a Format object. Using a fluent interface, format properties of the table, e.g., borders, font styles, colors etc.

  universal_constants.format()
    .font_style({FontStyle::bold})
    .border_top(" ")
    .border_bottom(" ")
    .border_left(" ")
    .border_right(" ")
    .corner(" ");

You can access rows in the table using Table[row_index]. This will return a Row object on which you can similarly call Row.format() to format properties of all the cells in that row.

Now, let's format the header of the table. The following code changes the font background of the header row to red, aligns the cell contents to center and applies a padding to the top and bottom of the row.

  universal_constants[0].format()
    .padding_top(1)
    .padding_bottom(1)
    .font_align(FontAlign::center)
    .font_style({FontStyle::underline})
    .font_background_color(Color::red);

Calling Table.column(index) will return a Column object. Similar to rows, you can use Column.format() to format all the cells in that column.

Now, let's change the font color of the second column to yellow:

  universal_constants.column(1).format()
    .font_color(Color::yellow);

You can access cells by indexing twice from a table: From a row using Table[row_index][col_index] or from a column using Table.column(col_index)[cell_index]. Just like rows, columns, and tables, you can use Cell.format() to format individual cells

  universal_constants[0][1].format()
    .font_background_color(Color::blue)
    .font_color(Color::white);
}

Print the table using the stream operator<< like so:

  std::cout << universal_constants << std::endl;

You could also use Table.print(stream) to print the table, e.g., universal_constants.print(std::cout).

Formatting Options

Style Inheritance Model

Formatting in tabulate follows a simple style-inheritance model. When rendering each cell:

Apply cell formatting if specified
If no cell formatting is specified, apply its parent row formatting
If no row formatting is specified, apply its parent table formatting
If no table formatting is specified, apply the default table formatting

This enables overriding the formatting for a particular cell even though row or table formatting is specified, e.g., when an entire row is colored yellow but you want a specific cell to be colored red.

Word Wrapping

tabulate supports automatic word-wrapping when printing cells.

Although word-wrapping is automatic, there is a simple override. Automatic word-wrapping is used only if the cell contents do not have any embedded newline \n characters. So, you can embed newline characters in the cell contents and enforce the word-wrapping manually.

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table table;

  table.add_row({"This paragraph contains a veryveryveryveryveryverylong word. The long word will "
                 "break and word wrap to the next line.",
                 "This paragraph \nhas embedded '\\n' \ncharacters and\n will break\n exactly "
                 "where\n you want it\n to\n break."});

  table[0][0].format().width(20);
  table[0][1].format().width(50);

  std::cout << table << std::endl;
}

The above table has 1 row and 2 columns.
The first cell has automatic word-wrapping.
The second cell uses the embedded newline characters in the cell contents - even though the second column has plenty of space (50 characters width), it uses user-provided newline characters to break into new lines and enforce the cell style.
NOTE: Whether word-wrapping is automatic or not, tabulate performs a trim operation on each line of each cell to remove whitespace characters from either side of line.

NOTE: Both columns in the above table are left-aligned by default. This, however, can be easily changed.

Font Alignment

tabulate supports three font alignment settings: left, center, and right. By default, all table content is left-aligned. To align cells, use .format().font_align(alignment).

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table movies;
  movies.add_row({"S/N", "Movie Name", "Director", "Estimated Budget", "Release Date"});
  movies.add_row({"tt1979376", "Toy Story 4", "Josh Cooley", "$200,000,000", "21 June 2019"});
  movies.add_row({"tt3263904", "Sully", "Clint Eastwood", "$60,000,000", "9 September 2016"});
  movies.add_row({"tt1535109", "Captain Phillips", "Paul Greengrass", "$55,000,000", " 11 October 2013"});

  // center align 'Director' column
  movies.column(2).format()
    .font_align(FontAlign::center);

  // right align 'Estimated Budget' column
  movies.column(3).format()
    .font_align(FontAlign::right);

  // right align 'Release Date' column
  movies.column(4).format()
    .font_align(FontAlign::right);

  // center-align and color header cells
  for (size_t i = 0; i < 5; ++i) {
    movies[0][i].format()
      .font_color(Color::yellow)
      .font_align(FontAlign::center)
      .font_style({FontStyle::bold});
  }

  std::cout << movies << std::endl;
}

Font Styles

tabulate supports 8 font styles: bold, dark, italic, underline, blink, reverse, concealed, crossed. Depending on the terminal (or terminal settings), some of these might not work.

To apply a font style, simply call .format().font_style({...}). The font_style method takes a vector of font styles. This allows to apply multiple font styles to a cell, e.g., bold and italic.

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table styled_table;
  styled_table.add_row({"Bold", "Italic", "Bold & Italic", "Blinking"});
  styled_table.add_row({"Underline", "Crossed", "Dark", "Bold, Italic & Underlined"});

  styled_table[0][0].format()
    .font_style({FontStyle::bold});

  styled_table[0][1].format()
    .font_style({FontStyle::italic});

  styled_table[0][2].format()
    .font_style({FontStyle::bold, FontStyle::italic});

  styled_table[0][3].format()
    .font_style({FontStyle::blink});

  styled_table[1][0].format()
    .font_style({FontStyle::underline});

  styled_table[1][1].format()
    .font_style({FontStyle::crossed});

  styled_table[1][2].format()
    .font_style({FontStyle::dark});


  styled_table[1][3].format()
    .font_style({FontStyle::bold, FontStyle::italic, FontStyle::underline});

  std::cout << styled_table << std::endl;

}

NOTE: Font styles are applied to the entire cell. Unlike HTML, you cannot currently apply styles to specific words in a cell.

Cell Colors

There are a number of methods in the Format object to color cells - foreground and background - for font, borders, corners, and column separators. Thanks to termcolor, tabulate supports 8 colors: grey, red, green, yellow, blue, magenta, cyan, and white. The look of these colors vary depending on your terminal.

For font, border, and corners, you can call .format().<element>_color(value) to set the foreground color and .format().<element>_background_color(value) to set the background color. Here's an example:

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table colors;

  colors.add_row({"Font Color is Red", "Font Color is Blue", "Font Color is Green"});
  colors.add_row({"Everything is Red", "Everything is Blue", "Everything is Green"});
  colors.add_row({"Font Background is Red", "Font Background is Blue", "Font Background is Green"});

  colors[0][0].format()
    .font_color(Color::red)
    .font_style({FontStyle::bold});
  colors[0][1].format()
    .font_color(Color::blue)
    .font_style({FontStyle::bold});
  colors[0][2].format()
    .font_color(Color::green)
    .font_style({FontStyle::bold});

  colors[1][0].format()
    .border_left_color(Color::red)
    .border_left_background_color(Color::red)
    .font_background_color(Color::red)
    .font_color(Color::red);

  colors[1][1].format()
    .border_left_color(Color::blue)
    .border_left_background_color(Color::blue)
    .font_background_color(Color::blue)
    .font_color(Color::blue);

  colors[1][2].format()
    .border_left_color(Color::green)
    .border_left_background_color(Color::green)
    .font_background_color(Color::green)
    .font_color(Color::green)
    .border_right_color(Color::green)
    .border_right_background_color(Color::green);

  colors[2][0].format()
    .font_background_color(Color::red)
    .font_style({FontStyle::bold});
  colors[2][1].format()
    .font_background_color(Color::blue)
    .font_style({FontStyle::bold});
  colors[2][2].format()
    .font_background_color(Color::green)
    .font_style({FontStyle::bold});

  std::cout << colors << std::endl;
}

Borders and Corners

tabulate allows for fine control over borders and corners. For each border and corner, you can set the text, color, and background color.

NOTE: You can use .corner(..), .corner_color(..), and .corner_background_color(..) to set a common style for all corners. Similarly, you can use .border(..), .border_color(..) and .border_background_color(..) to set a common style for all borders.

NOTE: Note the use of .format().multi_byte_characters(true). Use this when you know your table has multi-byte characters. This is an opt-in because the calculation of column width when dealing with multi-byte characters is more involved and you don't want to pay the performance penalty unless you need it. Just like any other format setting, you can set this at the table-level, row-level, or on a per-cell basis.

Here's an example where each border and corner is individually styled:

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table table;

  table.add_row({"ᛏᚺᛁᛊ ᛁᛊ ᚨ ᛊᛏᛟᚱy ᛟᚠᚨ ᛒᛖᚨᚱ ᚨᚾᛞ\n"
                 "ᚨ ᚹᛟᛚᚠ, ᚹᚺᛟ ᚹᚨᚾᛞᛖᚱᛖᛞ ᛏᚺᛖ\n"
                 "ᚱᛖᚨᛚᛗᛊ ᚾᛁᚾᛖ ᛏᛟ ᚠᚢᛚᚠᛁᛚᛚ ᚨ ᛈᚱᛟᛗᛁᛊᛖ\n"
                 "ᛏᛟ ᛟᚾᛖ ᛒᛖᚠᛟᚱᛖ; ᛏᚺᛖy ᚹᚨᛚᚲ ᛏᚺᛖ\n"
                 "ᛏᚹᛁᛚᛁᚷᚺᛏ ᛈᚨᛏᚺ, ᛞᛖᛊᛏᛁᚾᛖᛞ ᛏᛟ\n"
                 "ᛞᛁᛊcᛟᚹᛖᚱ ᛏᚺᛖ ᛏᚱᚢᛏᚺ\nᛏᚺᚨᛏ ᛁᛊ ᛏᛟ cᛟᛗᛖ."});

  table.format()
      .multi_byte_characters(true)
      // Font styling
      .font_style({FontStyle::bold, FontStyle::dark})
      .font_align(FontAlign::center)
      .font_color(Color::red)
      .font_background_color(Color::yellow)
      // Corners
      .corner_top_left("ᛰ")
      .corner_top_right("ᛯ")
      .corner_bottom_left("ᛮ")
      .corner_bottom_right("ᛸ")
      .corner_top_left_color(Color::cyan)
      .corner_top_right_color(Color::yellow)
      .corner_bottom_left_color(Color::green)
      .corner_bottom_right_color(Color::red)
      // Borders
      .border_top("ᛜ")
      .border_bottom("ᛜ")
      .border_left("ᚿ")
      .border_right("ᛆ")
      .border_left_color(Color::yellow)
      .border_right_color(Color::green)
      .border_top_color(Color::cyan)
      .border_bottom_color(Color::red);

  std::cout << table << std::endl;
}

Range-based Iteration

Hand-picking and formatting cells using operator[] gets tedious very quickly. To ease this, tabulate supports range-based iteration on tables, rows, and columns. Quickly iterate over rows and columns to format cells.

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table table;

  table.add_row({"Company", "Contact", "Country"});
  table.add_row({"Alfreds Futterkiste", "Maria Anders", "Germany"});
  table.add_row({"Centro comercial Moctezuma", "Francisco Chang", "Mexico"});
  table.add_row({"Ernst Handel", "Roland Mendel", "Austria"});
  table.add_row({"Island Trading", "Helen Bennett", "UK"});
  table.add_row({"Laughing Bacchus Winecellars", "Yoshi Tannamuri", "Canada"});
  table.add_row({"Magazzini Alimentari Riuniti", "Giovanni Rovelli", "Italy"});

  // Set width of cells in each column
  table.column(0).format().width(40);
  table.column(1).format().width(30);
  table.column(2).format().width(30);

  // Iterate over cells in the first row
  for (auto& cell : table[0]) {
    cell.format()
      .font_style({FontStyle::underline})
      .font_align(FontAlign::center);
  }

  // Iterator over cells in the first column
  for (auto& cell : table.column(0)) {
    if (cell.get_text() != "Company") {
      cell.format()
        .font_align(FontAlign::right);
    }
  }

  // Iterate over rows in the table
  size_t index = 0;
  for (auto& row : table) {
    row.format()
      .font_style({FontStyle::bold});

    // Set blue background color for alternate rows
    if (index > 0 && index % 2 == 0) {
      for (auto& cell : row) {
        cell.format()
          .font_background_color(Color::blue);
      }      
    }
    index += 1;
  }

  std::cout << table << std::endl;
}

Nested Tables

Table.add_row(...) takes either a std::string or a tabulate::Table. This can be used to nest tables within tables. Here's an example program that prints a UML class diagram using tabulate. Note the use of font alignment, style, and width settings to generate a diagram that looks centered and great.

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table class_diagram;

  // Global styling
  class_diagram.format().font_style({FontStyle::bold}).font_align(FontAlign::center).width(60);

  // Animal class
  Table animal;
  animal.add_row({"Animal"});
  animal[0].format().font_align(FontAlign::center);

  // Animal properties nested table
  Table animal_properties;
  animal_properties.format().width(20);
  animal_properties.add_row({"+age: Int"});
  animal_properties.add_row({"+gender: String"});
  animal_properties[1].format().hide_border_top();

  // Animal methods nested table
  Table animal_methods;
  animal_methods.format().width(20);
  animal_methods.add_row({"+isMammal()"});
  animal_methods.add_row({"+mate()"});
  animal_methods[1].format().hide_border_top();

  animal.add_row({animal_properties});
  animal.add_row({animal_methods});
  animal[2].format().hide_border_top();

  class_diagram.add_row({animal});

  // Add rows in the class diagram for the up-facing arrow
  // THanks to center alignment, these will align just fine
  class_diagram.add_row({"▲"});
  class_diagram[1][0].format().hide_border_top().multi_byte_characters(true); // ▲ is multi-byte
  
  class_diagram.add_row({"|"});
  class_diagram[2].format().hide_border_top();
  class_diagram.add_row({"|"});
  class_diagram[3].format().hide_border_top();

  // Duck class
  Table duck;
  duck.add_row({"Duck"});
  duck[0].format().font_align(FontAlign::center);

  // Duck proeperties nested table
  Table duck_properties;
  duck_properties.format().width(40);
  duck_properties.add_row({"+beakColor: String = \"yellow\""});

  // Duck methods nested table
  Table duck_methods;
  duck_methods.format().width(40);
  duck_methods.add_row({"+swim()"});
  duck_methods.add_row({"+quack()"});
  duck_methods[1].format().hide_border_top();

  duck.add_row({duck_properties});
  duck.add_row({duck_methods});
  duck[2].format().hide_border_top();

  class_diagram.add_row({duck});
  class_diagram[4].format().hide_border_top();

  std::cout << class_diagram << std::endl;
}

UTF-8 Support

In *nix, wcswidth is used to compute the display width of multi-byte characters. Column alignment works well when your system supports the necessary locale, e.g., I've noticed on MacOS 10 there is no Arabic locale (searched with locale -a) and this ends up causing alignment issues when using Arabic text, e.g., "ٲنَا بحِبَّك (Ana bahebak)" in tables.

The following table prints the phrase I love you in different languages. Note the use of .format().multi_byte_characters(true) for the second column. Remember to do this when dealing with multi-byte characters.

#include <tabulate/table.hpp>
using namespace tabulate;

int main() {
  Table table;

  table.format().corner("♥")
    .font_style({FontStyle::bold})
    .corner_color(Color::magenta)
    .border_color(Color::magenta);

  table.add_row({"English", "I love you"});
  table.add_row({"French", "Je t’aime"});
  table.add_row({"Spanish", "Te amo"});
  table.add_row({"German", "Ich liebe Dich"});
  table.add_row({"Mandarin Chinese", "我爱你"});
  table.add_row({"Japanese", "愛してる"});
  table.add_row({"Korean", "사랑해 (Saranghae)"});
  table.add_row({"Greek", "Σ΄αγαπώ (Se agapo)"});
  table.add_row({"Italian", "Ti amo"});
  table.add_row({"Russian", "Я тебя люблю (Ya tebya liubliu)"});
  table.add_row({"Hebrew", "אני אוהב אותך (Ani ohev otakh)"});

  // Column 1 is using mult-byte characters
  table.column(1).format()
    .multi_byte_characters(true);

  std::cout << table << std::endl;
}

You can explicitly set the locale for a cell using .format().locale(value). Note that the locale string is system-specific. So, the following code might throw std::runtime_error locale::facet::_S_create_c_locale name not valid on your system.

  // Set English-US locale for first column
  table.column(0).format().locale("en_US.UTF-8");
  table[0][1].format().locale("en_US.UTF-8");

  // Set locale for individual cells
  table[1][1].format().locale("fr_FR.UTF-8");  // French
  table[2][1].format().locale("es_ES.UTF-8");  // Spanish
  table[3][1].format().locale("de_DE.UTF-8");  // German
  table[4][1].format().locale("zh_CN.UTF-8");  // Chinese
  table[5][1].format().locale("ja_JP.UTF-8");  // Japanese
  table[6][1].format().locale("ko_KR.UTF-8");  // Korean
  table[7][1].format().locale("el_GR.UTF-8");  // Greek
  table[8][1].format().locale("it_IT.UTF-8");  // Italian
  table[9][1].format().locale("ru_RU.UTF-8");  // Russian
  table[10][1].format().locale("he_IL.UTF-8"); // Hebrew

Exporters

Markdown

Tables can be exported to GitHub-flavored markdown using a MarkdownExporter. Simply create an exporter object and call exporter.dump(table) to generate a Markdown-formatted std::string.

#include <tabulate/markdown_exporter.hpp>
using namespace tabulate;

int main() {
  Table movies;
  movies.add_row({"S/N", "Movie Name", "Director", "Estimated Budget", "Release Date"});  
  movies.add_row({"tt1979376", "Toy Story 4", "Josh Cooley", "$200,000,000", "21 June 2019"});
  movies.add_row({"tt3263904", "Sully", "Clint Eastwood", "$60,000,000", "9 September 2016"});
  movies.add_row(
      {"tt1535109", "Captain Phillips", "Paul Greengrass", "$55,000,000", " 11 October 2013"});

  // center align 'Director' column
  movies.column(2).format().font_align(FontAlign::center);

  // right align 'Estimated Budget' column
  movies.column(3).format().font_align(FontAlign::right);

  // right align 'Release Date' column
  movies.column(4).format().font_align(FontAlign::right);

  // Color header cells
  for (size_t i = 0; i < 5; ++i) {
    movies[0][i].format().font_color(Color::yellow).font_style({FontStyle::bold});
  }

  // Export to Markdown
  MarkdownExporter exporter;
  auto markdown = exporter.dump(movies);

  // tabulate::table
  std::cout << movies << "\n\n";

  // Exported Markdown
  std::cout << markdown << std::endl;
}

The above table renders in Markdown like below.

NOTE: Unlike tabulate, you cannot align individual cells in Markdown. Alignment is on a per-column basis. Markdown allows a second header row where such column-wise alignment can be specified. The MarkdownExporter uses the formatting of the header cells in the original tabulate::Table to decide how to align each column. As per the Markdown spec, columns are left-aligned by default.

S/N	Movie Name	Director	Estimated Budget	Release Date
tt1979376	Toy Story 4	Josh Cooley	$200,000,000	21 June 2019
tt3263904	Sully	Clint Eastwood	$60,000,000	9 September 2016
tt1535109	Captain Phillips	Paul Greengrass	$55,000,000	11 October 2013

AsciiDoc

Tabulate can export tables as AsciiDoc using an AsciiDocExporter.

#include <tabulate/asciidoc_exporter.hpp>
using namespace tabulate;

int main() {
  Table movies;
  movies.add_row({"S/N", "Movie Name", "Director", "Estimated Budget", "Release Date"});
  movies.add_row({"tt1979376", "Toy Story 4", "Josh Cooley", "$200,000,000", "21 June 2019"});
  movies.add_row({"tt3263904", "Sully", "Clint Eastwood", "$60,000,000", "9 September 2016"});
  movies.add_row(
      {"tt1535109", "Captain Phillips", "Paul Greengrass", "$55,000,000", " 11 October 2013"});

  // center align 'Director' column
  movies.column(2).format().font_align(FontAlign::center);

  // right align 'Estimated Budget' column
  movies.column(3).format().font_align(FontAlign::right);

  // right align 'Release Date' column
  movies.column(4).format().font_align(FontAlign::right);

  movies[1][2].format().font_style({FontStyle::bold, FontStyle::italic});
  movies[2][1].format().font_style({FontStyle::italic});

  // Color header cells
  for (size_t i = 0; i < 5; ++i) {
    movies[0][i]
        .format()
        .font_color(Color::white)
        .font_style({FontStyle::bold})
        .background_color(Color::blue);
  }

  AsciiDocExporter exporter;
  auto asciidoc = exporter.dump(movies);

  // tabulate::table
  std::cout << movies << "\n\n";

  // Exported AsciiDoc
  std::cout << asciidoc << std::endl;
}

Below is the export of the example above:

[cols="<,<,^,>,>"]
|===
|*S/N*|*Movie Name*|*Director*|*Estimated Budget*|*Release Date*

|tt1979376|Toy Story 4|*_Josh Cooley_*|$200,000,000|21 June 2019
|tt3263904|_Sully_|Clint Eastwood|$60,000,000|9 September 2016
|tt1535109|Captain Phillips|Paul Greengrass|$55,000,000| 11 October 2013
|===

The rendered output you can see here: http://tpcg.io/pbbfU3ks

NOTE Alignment is only supported per column. The font styles FontStyle::bold and FontStyle::italic can be used for each cell, also in combination.

Building Samples

There are a number of samples in the samples/ directory, e.g., Mario. You can build these samples by running the following commands.

mkdir build
cd build
cmake -DSAMPLES=ON -DUSE_CPP17=ON ..
make

Note the USE_CPP17 variable. Tabulate uses std::variant and std::optional. If you do not have C++17 compiler support for these data structures, build without this flag. Tabulate will then use variant-lite and optional-lite.

Hello there,

Thanks very much for this library. I'm working on bindings for the R language. I encountered this behavior where modifying hide_border_bottom() won't modify the output if the table has been printed some time before.

For example:

#include <tabulate/table.hpp>
using namespace tabulate;
using Row_t = Table::Row_t;

int main() {
  Table table;
  table.add_row(Row_t{"hello"});
  table.add_row(Row_t{"world"});

  std::cout << table << std::endl;

  table.format().hide_border_bottom();

  std::cout << table << std::endl;

  table.format().width(50);

  std::cout << table << std::endl;
}

Returns:

+-------+
| hello |
+-------+
| world |
+-------+
+-------+
| hello |
+-------+
| world |
+-------+
+--------------------------------------------------+
| hello                                            |
+--------------------------------------------------+
| world                                            |

Weird exeption when using with OpenGL 4.3

Whenever I try to create a table and show it, it will do so. But then it will throw me an exception in my case that the position of my OpenGL framebuffer object could not be read. I tried both c++14 and c++17 and it's a x64 bit executable if that matters.

(Win32): "C:\Windows\System32\TextInputFramework.dll" loaded. Exception thrown at 0x00007FF6D4FC4D3E in .exe: 0xC0000005: access violation at position 0x0000000000000000.

How to give array as an input in table.add_row()?

Hey just want to know is there any facility to pass an array or vector to table.add_row() so that required row is generated from arrray/vector itself?

Put "requires C++17" with variant and optional utilities support

Modern C++ is C++17 however on the internet "modern" is synonymous with C++11 at minimum. I didn't see any notes anywhere trying to compile but #include <variant> and #include <optional> gave it away...

On that same note, my mingw tools for gcc on windows have the std::optional utility under experimental/*.

I don't think there's a substitute for variant under experimental but a way to be able to swap it out (and optional too) for a custom structures could be achieved for those < C++17. Variants and optional are very simple structures. They're not fundamentally difficult to write and would open the lib up to C++14 at least.

Question - Dynamically Change the tables Content

Dear Contributors,

Thanks for your useful library, I am trying to use this table objects in real-time terminal application and show the columns contents dynamically, when they changed, for example during the execution the contents of tables needs to change (like top command it refreshed the generated output), is it possible to do it ?

Thanks :)

format border commands have no effect

I'm trying to print tables without any border characters. When I use the .format().border_top(" ") etc type of commands, it has no effect and always prints the default +----+ type borders. Similarly using output_table.format().hide_border(); also has no effect, and still prints with the default borders. Am I using this wrong or is it a bug?

My test environment: MSYS2/mingw64, (https://www.msys2.org/) g++.exe (Rev5, Built by MSYS2 project) 10.3.0 p-ranav/tabulate-master,2021/08/15

//My test code: #include "tabulate/table.hpp" #include int main() { tabulate::Table table; table.add_row({"001", "Jack", "is", "a good man"}); std::cout << table << std::endl; return 0; }

//My cmake code: set(APP_NAME "test_make_table") add_executable(${APP_NAME} main.cpp ) target_include_directories(${APP_NAME} PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/party3/tabulate-master/include ) target_compile_features(${APP_NAME} PUBLIC cxx_std_17 )

I build it with command "cmake --build build", it build pass. but when I run my app, error happened as follow: terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid

New tagged version on github?

Hey @p-ranav, would be nice to have a new version of tabulate on conda :)

I can of course create the new version on conda, but for that I need a new tagged version on github.

Lemme know if you want any help to get this going.

Thanks!

add_row signature changed in a backward-incompatible way in 1.3

First, we are super grateful for this package which is super nice!

FYI, it seems that this change is backward incompatible because of the change in the signature.

Maybe this should have been a 2.0 change?

Make tabulate compatible with mac's SDK 10.9

In our project we have a restriction that doesn't allow us to use a macOS SDK older than 10.9. The problem is that 10.9 doesn't offer full support to c++ 17 features, so things like optional and variant won't work well.

In order for it to work in 10.9 I had to make some changes, there is no value() method for optional and no get for variant, fortunately it's possible to use the equivalents * and get_info, and that's what I'm doing in this PR.

the github link isn't underlined or in italic either. Usual visual studio 16.0.29709

ps. is there a single header available?

Using tabulate in different Translation Unit leads to multiple definition at link time

Use Tabulate in two different .cpp and link the result leads to multiple definition errors. I think most of the functions in the header shoudl be marked inline.

Add option to remove entire columns

Hi, i couldnt find a way to remove a column after creating and populating a Table object. This is useful when i have a column that had empty entries in all rows and its unnecessary to print it.

Thanks for any help :)

Option to not strip leading (or trailing) whitespace in line-wrapped text?

I believe this is a feature request, but a workaround or solution would be great if one exists: an option/method to preserve leading whitespace would be desirable when markup (XML, JSON) snippets are the cell contents.

Perhaps we could have:

Format::enable_trim(bool en) { enable_trim_left(en); enable_trim_right(en) };
Format::enable_trim_left(bool);
Format::enable_trim_right(bool);
// or
enum class TrimDir{ none = 0, left = 1, right = 2, both = left | right /* remains default */};
Format::enable_trim(TrimDir);

// example usage
universal_contants.format()
  .width(50)
  .enable_trim(false);
// or
universal_contants.format()
  .width(50)
  .enable_trim(TrimDir::right); // better for JSON formatting

Not sure I can think of a good use case for keeping trailing whitespace... but there's probably one somewhere?
