Creating PDF documents with tables in Ruby, Rails

I started to use "Ruby FPDF":http://zeropluszero.com/software/fpdf/ to create PDF documents from our new Rails application "MojGost.com":http://www.mojgost.com. Ruby FPFD like it's "PHP counterpart":http://www.fpdf.org/ does not have methods for creating tables. However, there are many examples and scripts available and that allowed me to quickly write small Ruby module which adds few methods for easy table creation.

Do not use 'puts' in Rails
