This utility allows you to render unicode-aided tables on the command line from your node.js scripts.
cli-table3 is based on (and api compatible with) the original cli-table,
and cli-table2, which are both
unmaintained. cli-table3 includes all the additional features from
cli-table2.
- Ability to make cells span columns and/or rows.
- Ability to set custom styles per cell (border characters/colors, padding, etc).
- Vertical alignment (top, bottom, center).
- Word wrapping options.
- More robust truncation of cell text that contains ansi color characters.
- Better handling of text color that spans multiple lines.
- API compatible with the original cli-table.
- Exhaustive test suite including the entire original cli-table test suite.
- Lots of examples auto-generated from the tests (basic, advanced).
- Customizable characters that constitute the table.
- Color/background styling the table through
colors.jsansis. - Column width customization
- Text truncation based on predefined widths
- Text alignment (left, right, center)
- Padding (left, right)
- Easy-to-use API
npm install cli-table3A portion of the unit test suite is used to generate examples:
- basic-usage - covers basic uses.
- advanced - covers using the new column and row span features.
This package is api compatible with the original cli-table. So all the original documentation still applies (copied below).
var Table = require('cli-table3');
// instantiate
var table = new Table({
head: ['TH 1 label', 'TH 2 label']
, colWidths: [100, 200]
});
// table is an Array, so you can `push`, `unshift`, `splice` and friends
table.push(
['First value', 'Second value']
, ['First value', 'Second value']
);
console.log(table.toString());var Table = require('cli-table3');
var table = new Table();
table.push(
{ 'Some key': 'Some value' }
, { 'Another key': 'Another value' }
);
console.log(table.toString());Cross tables are very similar to vertical tables, with two key differences:
- They require a
headsetting when instantiated that has an empty string as the first header - The individual rows take the general form of { "Header": ["Row", "Values"] }
var Table = require('cli-table3');
var table = new Table({ head: ["", "Top Header 1", "Top Header 2"] });
table.push(
{ 'Left Header 1': ['Value Row 1 Col 1', 'Value Row 1 Col 2'] }
, { 'Left Header 2': ['Value Row 2 Col 1', 'Value Row 2 Col 2'] }
);
console.log(table.toString());The chars property controls how the table is drawn:
var table = new Table({
chars: { 'top': '═' , 'top-mid': '╤' , 'top-left': '╔' , 'top-right': '╗'
, 'bottom': '═' , 'bottom-mid': '╧' , 'bottom-left': '╚' , 'bottom-right': '╝'
, 'left': '║' , 'left-mid': '╟' , 'mid': '─' , 'mid-mid': '┼'
, 'right': '║' , 'right-mid': '╢' , 'middle': '│' }
});
table.push(
['foo', 'bar', 'baz']
, ['frob', 'bar', 'quuz']
);
console.log(table.toString());
// Outputs:
//
//╔══════╤═════╤══════╗
//║ foo │ bar │ baz ║
//╟──────┼─────┼──────╢
//║ frob │ bar │ quuz ║
//╚══════╧═════╧══════╝Empty decoration lines will be skipped, to avoid vertical separator rows just set the 'mid', 'left-mid', 'mid-mid', 'right-mid' to the empty string:
var table = new Table({ chars: {'mid': '', 'left-mid': '', 'mid-mid': '', 'right-mid': ''} });
table.push(
['foo', 'bar', 'baz']
, ['frobnicate', 'bar', 'quuz']
);
console.log(table.toString());
// Outputs: (note the lack of the horizontal line between rows)
//┌────────────┬─────┬──────┐
//│ foo │ bar │ baz │
//│ frobnicate │ bar │ quuz │
//└────────────┴─────┴──────┘By setting all chars to empty with the exception of 'middle' being set to a single space and by setting padding to zero, it's possible to get the most compact layout with no decorations:
var table = new Table({
chars: { 'top': '' , 'top-mid': '' , 'top-left': '' , 'top-right': ''
, 'bottom': '' , 'bottom-mid': '' , 'bottom-left': '' , 'bottom-right': ''
, 'left': '' , 'left-mid': '' , 'mid': '' , 'mid-mid': ''
, 'right': '' , 'right-mid': '' , 'middle': ' ' },
style: { 'padding-left': 0, 'padding-right': 0 }
});
table.push(
['foo', 'bar', 'baz']
, ['frobnicate', 'bar', 'quuz']
);
console.log(table.toString());
// Outputs:
//foo bar baz
//frobnicate bar quuzYou can colorize the text in the table head and the table border with 16 named colors or with truecolor using a hex code. The color and styles can be combined.
See the full list of base named colors and styles.
To apply a custom truecolor, use the format hex(CODE) for foreground and bgHex(CODE) for background,
where CODE is a 3- or 6-digit hexadecimal code, e.g., hex(#FFA500), hex(#A7E), bgHex(#FF69B4), bgHex(#49B).
Use the style.head[] option to style text in the table header.
For example, the header text in base color green and styled as bold :
var table = new Table({
head: ['Name', 'Age'],
style: {
head: ['green', 'bold'],
}
});
table.push(['Walter White', '50']);
console.log(table.toString());Outputs:
For example, the header text in truecolor orange and styled as italic:
style: {
head: ['hex(#FFA500)', 'italic'],
}
Use the style.border[] option to specify a border color.
For example, the header text in truecolor orange and the border in truecolor gold:
style: {
border: ['hex(#FFD700)'],
head: ['hex(#FFA500)', 'italic'],
}
To colorize cells can be used ansis, which is already included in this package as an optional dependency.
For example, apply an individual color to the single cell in the table body:
var ansi = require('ansis');
var Table = require('cli-table3');
var table = new Table({
head: ['Name', 'Age'],
style: {
border: ['hex(#FFD700)'],
head: ['hex(#FFA500)', 'italic'],
}
});
table.push(
// apply a color to cells
[ansi.green('Walter White'), ansi.red('50')],
[ansi.hex('#FF69B4')('Jesse Pinkman'), ansi.blueBright('24')],
);
console.log(table.toString());Outputs:
For example, colorize the table body with one color:
var { green } = require('ansis'); // use a named import when using a few colors
var Table = require('cli-table3');
var table = new Table({
head: ['Name', 'Age'],
style: {
border: ['hex(#FFD700)'],
head: ['hex(#FFA500)', 'italic'],
}
});
table.push(
['Walter White', '50'],
['Jesse Pinkman', '24'],
);
var output = green(table.toString()); // colorize the whole table
console.log(output);Outputs:
To specify the background color you can use a color name with the bg prefix, e.g., bgGreen, bgGreenBright or gbHex() for truecolor.
For example, add a background color to the example above:
var { green } = require('ansis');
var Table = require('cli-table3');
var table = new Table({
head: ['Name', 'Age'],
style: {
border: ['hex(#FFD700)'],
head: ['hex(#FFA500)', 'italic'],
}
});
table.push(
['Walter White', '50'],
['Jesse Pinkman', '24'],
);
var output = green.bgHex('#3d239d')(table.toString()); // <- add a background to the table
console.log(output);Outputs:
Later versions of cli-table3 supporting debugging your table data.
Enable and use debugging:
var table = new Table({ debug: 1 });
table.push([{}, {},}); // etc.
console.log(table.toString());
table.messages.forEach((message) => console.log(message));
If you are rendering multiple tables with debugging on run Table.reset() after
rendering each table.
