JLabel或JTable单元上的ActionListener

怎么样：

table.addMouseListener(new MouseAdapter() {  public void mouseClicked(MouseEvent e) {    if (e.getClickCount() == 2) {      JTable target = (JTable)e.getSource();      int row = target.getSelectedRow();      int column = target.getSelectedColumn();      // do some action if appropriate column    }  }});
