jtable.addMouseListener(new MouseAdapter() {
   public void mousePressed(MouseEvent evt) {
     if (evt.isTrigerPopup())
       doPopup(evt);
   }
   public void mouseReleased(MouseEvent evt) {
     if (evt.isTrigerPopup())
       doPopup(evt);
   }
   private void doPopup(MouseEvent evt) {
     JPopupMenu jpm = getPopupMenu(evt);
     if (jpm != null)
       jpm.showComponenent(evt.getSource(), evt.getPoint().x,
evt.getPoint().y);
   }
   private JPopupMenu getPopupMenu(MouseEvent evt) {
     int row = jtable.rowAtPoint(evt.getPoint());
     int column = jtable.columnAtPoint(evt.getPoint());

     if (row < 0 || column < 0)
       return null;

     JPopuMenu jpm = new JPopupMenu();

     Object o = jtable.getValueAt(row, column);
     if (testOn(o)) {
       jpm.add(...);
     }
     ...

     return jpm;
   }
});
