This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I've done this in the past, but not with tomahawk dataTable. So perhaps this might not help, but then again, maybe it does.
I used myFaces dataTable. And I just sorted the List on the backing bean. So in the header of the column I have 2 commands (little up and down arrows) that call a sortXXXAscending or sortXXXDescending method on the backing bean. Then this method just uses the Collections.sort method to sort the actual List containing the data.
