Report Generator

I need to make a report engine using a couple of mySQL tables. What I'm working on is a "add/remove" select-option list with the column names so the user can customize their own report. They can add/remove the columns in the order that they want, then order by a column asc/desc. The report page will have the column headers then the data. It's taking me a little time to write this and I'm wondering if their is something like this out there already I can use? John
