Sometimes I hand write pseudocode, but I call it an "algorithm". Then I implement the algorithm in Perl and run/debug/write until it works. I don't focus on optimiziation if it's outside my normal idiomatic domain. I am telling you this because I think it's most efficient for all of us, but you especially you, to come here during the phase where maybe you've run into an issue with your real code. e.g., "I can't get this to work" or "I don't know how to do this part", etc.
Back to your question. What "table" do you mean? database, html, excel, csv? In all of those cases there is a Perl module on CPAN that will help you. In the case of it being your kitchen table, some monks know a little about wood working as well xD
