Overview

A Style object holds all the formatting information for a Table object

To create a table with a certain style, use either the constructor option :style, the Table#style object or the Table#style= method

All these examples have the same effect:

# by constructor
@table = Table.new(:style => {:padding_left => 2, :width => 40})

# by object
@table.style.padding_left = 2
@table.style.width = 40

# by method
@table.style = {:padding_left => 2, :width => 40}

To set a default style for all tables created afterwards use Style.defaults=

Terminal::Table::Style.defaults = {:width => 80}
