I can't create a table as described here: http://prawn.majesticseacreature.com/
with version 0.4.1

-- Flexible table drawing

Prawn has built in support for rendering text in the form of tables, providing basic reporting functionality. This lets users focus on customizing their documents rather than forcing them to write a ton of low level graphics drawing code.

Prawn::Document.generate("fancy_table.pdf") do

data = [["Gregory Brown", "gregory.t.brown@fakemail.test" ],

      ["James Healy"  , "jimmy@fakemail.test"           ],
      ["Ross Perot"   , "ross@fakemail.test"            ],
      ["Al Gore"      , "al@fakemail.test"              ],
      ["Ralph Nader"  , "ralph@fakemail.test"           ]]

table data,

:position           => :center,
:headers            => ["Name", "Email"],
:row_colors         => ["ffffff","ffff00"],
:vertical_padding   => 5,
:horizontal_padding => 3

end

------------- end paste

This code does not work, table is not a method of Prawn::Document

Please update this doco :)
