# 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 <tt>:style</tt>, 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}
#
