Do you mean to stop them selecting unused day cells? Use a custom
ListSelectionModel that only allows valid cells to be selected. Remember
that you need two selection models - one for rows, one for columns - set the
'rows' one on the table, and the columns one on the TableColumnModel.

I suspect that you are not listening to events from the TableColumnModel.

I use a JTable perfectly well. I'd expect not doing so would create a lot of
extra work.

There may be one on IBM's developerWorks/alphaWorks sites, I'm not sure -
I've written my own, but unfortunately cannot make the code public.
