cli-table3
===============================================================================
[](https://www.npmjs.com/package/cli-table3)
[](https://travis-ci.com/cli-table/cli-table3)
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](https://github.com/Automattic/cli-table),
and [cli-table2](https://github.com/jamestalmage/cli-table2), which are both
unmaintained. `cli-table3` includes all the additional features from
`cli-table2`.
## Features not in the original cli-table
- 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).
- Automatic word wrapping.
- 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](https://github.com/cli-table/cli-table3/blob/master/basic-usage.md), [advanced](https://github.com/cli-table/cli-table3/blob/master/advanced-usage.md)).
## Features
- Customizable characters that constitute the table.
- Color/background styling in the header through
[colors.js](http://github.com/marak/colors.js)
- Column width customization
- Text truncation based on predefined widths
- Text alignment (left, right, center)
- Padding (left, right)
- Easy-to-use API
## Installation
```bash
npm install cli-table3
```
## How to use
A portion of the unit test suite is used to generate examples:
- [basic-usage](https://github.com/cli-table/cli-table3/blob/master/basic-usage.md) - covers basic uses.
- [advanced](https://github.com/cli-table/cli-table3/blob/master/advanced-usage.md) - covers using the new column and row span features.
This package is api compatible with the original [cli-table](https://github.com/Automattic/cli-table).
So all the original documentation still applies (copied below).
### Horizontal Tables
```javascript
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());
```
### Vertical Tables
```javascript
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
Cross tables are very similar to vertical tables, with two key differences:
1. They require a `head` setting when instantiated that has an empty string as the first header
2. The individual rows take the general form of { "Header": ["Row", "Values"] }
```javascript
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());
```
### Custom styles
The ```chars``` property controls how the table is drawn:
```javascript
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:
```javascript
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:
```javascript
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 quuz
```
## Build Targets
Clone the repository and run `yarn install` to install all its submodules, then run one of the following commands:
###### Run the tests with coverage reports.
```bash
$ yarn test:coverage
```
###### Run the tests every time a file changes.
```bash
$ yarn test:watch
```
###### Update the documentation.
```bash
$ yarn docs
```
