How do you have sorting arrows without using jQuery UI?

iamrook

I am just using my own css to customize datatables and want to create sort arrows next to the column headers, but I also don't want to muck up all of the html with jquery ui classes when I am not using them (and it also screws up some of my styles).

The thing is the SPAN for the icon doesn't show up in the TH without doing "bJQueryUI": true; in the datatable settings.

Any suggestions? Thanks!
