title: JTable cell listener?
body: <p>I am using a JTable.  I need to get a notification whenever a cell
  selection change.   I tried to use the ListSelectionListener but 
  I only get notification when the row selection change.  If I select a
  new column on the same row, I don't get notify.  I need to know when
  the cell is selected, not when the cell is changed.  Is there a listener that I can use to do this ?</p>
