侦听器需要什么来检测JTable单元格是否已被双击，从而切换到编辑模式？

JTable table = new JTable(data, columnNames);
table.addMouseListener(new MouseAdapter() {
    private Timer timer;
    private boolean doubleClicked = false;

    @Override
    public void mouseClicked(MouseEvent e) {
        if (e.getClickCount() == 2) {
            if (timer != null && timer.isRunning()) {
                timer.stop();
                doubleClicked = true;

                int row = table.rowAtPoint(e.getPoint());
                int column = table.columnAtPoint(e.getPoint());
                if (table.editCellAt(row, column)) {
                    Component editor = table.getEditorComponent();
                    editor.requestFocusInWindow();
                }
            } else {
                doubleClicked = false;
                timer = new Timer(200, new ActionListener() {
                    @Override
                    public void actionPerformed(ActionEvent evt) {
                        if (!doubleClicked) {
                            timer.stop();
                        }
                    }
                });
                timer.setRepeats(false);
                timer.start();
            }
        }
    }
});
