CLI Table [![NPM Version](http://badge.fury.io/js/cli-table.svg)](http://badge.fury.io/js/cli-table) [![Build Status](https://secure.travis-ci.org/Automattic/cli-table.svg)](http://travis-ci.org/Automattic/cli-table)
=========

This utility allows you to render unicode-aided tables on the command line from
your node.js scripts.

## 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-table
```

## How to use

### Horizontal Tables
```javascript
var Table = require('cli-table');

// 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());
```

### Initializing rows in the constructore

Optionally you can initialize rows in the constructors directly - comes in handy for smaller tables:

```
new Table({
  rows: [
      ['foo', '7 minutes ago']
    , ['bar', '8 minutes ago']
  ]
})
```

### Vertical Tables
```javascript
var Table = require('cli-table');
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-table');
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
```
