使用JRadioButton作为单元格渲染器停止JTable中的单元格编辑

在此代码中,鼠标单击表格单元格仍处于编辑模式且JRadioButton处于错误状态。我必须按ESC键以退出编辑模式,让渲染器在单元格中呈现JRadioButton的正确状态。有人知道我需要在代码中实现什么才能让单元格编辑器发布编辑模式吗?

public class Test extends JFrame {

    JTable myTable = new JTable();

    public Test() {
        this.setSize(150, 150);
        this.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
                dispose();
                System.exit(0);
            }
        });
        setVisible(true);
        myTable.setModel(new MyModel());
        myTable.getColumnModel().getColumn(0).setCellRenderer(new MyRenderer());
        myTable.getColumnModel().getColumn(0).setCellEditor(new MyEditor());
        myTable.setTableHeader(null);
        this.add(myTable);
    }
