Cross Tabulation from Google Spreadsheet (using google table)

Hi there, I have some data in a google spreadsheet, and I want to create a cross tabulation from this data... something like this: [login to view URL] so user will select the row and column questions and the output will be a table with counts and percentages... plus we might need some filters like date ranges, etc (that I dont think will be an issue as Google Visualization already provides that)... Please let me know if you would be able to help? Thanks
