Comparing independent table calculation results from different sheets

Just as I had finished my blog on how to transfer results of a table calculation from one sheet to another, a new but related question popped up on the forums. This time, the user wanted to compare two independent rankings. I.e. he did not want to compare on a product level but instead he wanted to compare Rank#1 from Ranking A to Rank#1 from Ranking B etc where both rankings could be based on completely independent filters.
