    How to use

    Horizontal Tables

    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());

    Vertical Tables

    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"] }
    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:

    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 quuz
