I have a pretty large table of data (approx. 20 columns and 150 rows, with each intersection cell having a data value of 0 to 5), and I want visitors to my website to be able to sort the table to their needs. For one example of the sorting that I'd like to make available: there would be a prompt for the user to pick three or four columns, and all of the rows would be sorted according to their total data value in those 3 or 4 columns.
I found a cheap software package that claims to be able to build this sort of sortable online table easily, but it's only for older versions of Windows. My main web-writing computer is an old Mac G4 powerbook running OSX10.4.1, and I just got a new PC running Windows 7 Pro. I did a bunch of Googling for similar software and came up with only confusion and dead ends. So if you know of a product I should be looking at (aside from a college course in MySQL

) please let me know.
And if you or someone you know can build such a thing not too expensively, let me know.
All advice welcomed and appreciated.
