如何通过按键盘上的DELETE删除JTable中的行

KeyListeners的一个问题是，要侦听的组件 必须 具有焦点。解决此问题的一种方法是使用键绑定。

例如，

  // assume JTable is named "table"  int condition = JComponent.WHEN_IN_FOCUSED_WINDOW;  InputMap inputMap = table.getInputMap(condition);  ActionMap actionMap = table.getActionMap();  // DELETE is a String constant that for me was defined as "Delete"  inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0), DELETE);  actionMap.put(DELETE, new AbstractAction() {     public void actionPerformed(ActionEvent e) {        // TODO: do deletion action here     }  });
