methods

var table = require('text-table')

var s = table(rows, opts={})

Return a formatted table string s from an array of rows and some options opts.

rows should be an array of arrays containing strings, numbers, or other printable values.

options can be:

• opts.hsep - separator to use between columns, default ' '

• opts.align - array of alignment types for each column, default ['l','l',...]

• opts.stringLength - callback function to use when calculating the string length

alignment types are:

• 'l' - left

• 'r' - right

• 'c' - center

• '.' - decimal

install

With npm do:

npm install text-table

Use with ANSI-colors

Since the string length of ANSI color schemes does not equal the length JavaScript sees internally it is necessary to pass the a custom string length calculator during the main function call.

See the test/ansi-colors.js file for an example.
