columnHeader

The columnHeader is an object which can have the following possible properties:

• name (string), required
• size (number)
• align (string), 'left', 'right' or 'center', default='left'
• color (string or function), function(val, row) { return color; }
• format (function), function(val, row) { return newVal; }

Multiple column headers can be passed,

tableaux({name: 'Title'}, {name: 'Author'}, {name: 'ISBN'})

writeFn(...columnValues)

The returned value is a function, each argument corresponds to a column,

var write = tableaux({name: 'Title'}, {name: 'Author'}, {name: 'ISBN'})

write('War and Peace', 'Leo Tolstoy', 9789722219242)

The writeFn also has several convenience methods

writeFn.dim(str)

Output the string with the dim ANSI escape code

writeFn.bold(str)

Output the string with the bright ANSI escape code

writeFn.newline()

Write a newline character (\n)

writeFn.spaces(n)

writeFn.arrow(leftPad = 3, rightPad = 1)

Output a ↳ character, specify leftPad and rightPad params for padding around the arrow

Example

var tableaux = require('tableaux')

var write = tableaux({name: 'Title'}, {name: 'Author'}, {name: 'ISBN'})

write('War and Peace', 'Leo Tolstoy', '9789722219242')
