Well, actually have no a faint idea about the cause of your problem. But
u can try this function:

   table.tableChanged(new TableModelEvent(  PARAMETERS  ));

though as far as i know it does practically the same fireXxx funcs do.
But anyway it might help. The other solution that would help almost 4
sure is setting model after each changing of the table
(setModel(MyTableModel)).

Hope this helped a bit.
