    # 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

    #
    #     # 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}
