Not sure if it will get you more marks? My approach so far has to keep it simple and only implement the requirements.
I think it's probably worth spending the time making sure that you've satisfied the UI requirements and have created a framework that will support future enhancement to the GUI.
Saying that I think there is possible justification for providing the functionality, as Row Sorting is mentioned in the
Java Look and Feel Guidelines.
Java Look and Feel Guidelines I guess if you think it's not much effort and you can implement in a way that your not going to lose mark then do it.
