class Terminal::Table::Style


Terminal::Table::Style.defaults = {:width => 80}
To set a default style for all tables created afterwards use Style.defaults=
@table.style = {:padding_left => 2, :width => 40}
# by method
@table.style.width = 40
@table.style.padding_left = 2
# by object
@table = Table.new(:style => {:padding_left => 2, :width => 40})
# by constructor
All these examples have the same effect:
option :style, the Table#style object or the Table#style= method
To create a table with a certain style, use either the constructor
A Style object holds all the formatting information for a Table object
