Question

我有一个JTable，它有几行，每行有一个按钮。不知怎的，我相信按钮不可点击。

这是我的代码：

public class JTableJButton {
    JFrame frame;
    JPanel panel;
    JButton button;
    JTable table;
    DefaultTableModel tableModel;

    public JTableJButton(){
        frame = new JFrame("Frame");
        panel = new JPanel();
        button = new JButton("Remove");
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(java.awt.event.ActionEvent arg0) {
                System.out.println("Pressed");
            }
        });

        String col[] = {"number", "name#", "button"};
        tableModel = new DefaultTableModel(col, 0);

        Object[] data1 = {"1", "name1", button};
        tableModel.addRow(data1);

        Object[] data2 = {"2", "name2", button};
        tableModel.addRow(data2);

        Object[] data3 = {"3", "name3", button};
        tableModel.addRow(data3);


        table = new JTable(tableModel){
         @Override
            public boolean isCellEditable(int row, int column) {
                //all cells false
                return false;
            }
        };


        TableCellRenderer buttonRenderer = new JTableButtonRenderer();
        table.getColumn("button").setCellRenderer(buttonRenderer);

        TableCellEditor editor = new myEditor();
        table.getColumn("button").setCellEditor(editor);

        panel.add(new JScrollPane(table));

        frame.add(panel);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(500, 200);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
    public static void main(String[] args) {
        // TODO code application logic here
        new JTableJButton();
    }


    private static class JTableButtonRenderer implements TableCellRenderer {        
        @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            JButton button = (JButton)value;
            return button;  
        }
    }

那么是否有任何想法让按钮工作并使其执行删除所选行等功能？

编辑：根据广告中提供的链接，我注意到我需要创建一个CellEditor类，如下所示：

public class myEditor extends AbstractCellEditor
                         implements TableCellEditor,
                                    ActionListener {

        private Object editorValue;


        @Override
        public Object getCellEditorValue() {
            return editorValue;
        }

        @Override
        public Component getTableCellEditorComponent(JTable jtable, Object o, boolean bln, int i, int i1) {

        }

        @Override
        public void actionPerformed(ActionEvent ae) {
            System.out.print("HI");
        }

    }

但我仍然迷失了，我不明白这些方法使按钮工作的程序。我读了How to Use Tables: Using Other Editors，但仍然无法根据我的情况弄清楚方法中必须包含哪些数据。任何人都可以提供任何例子，只是为了让我知道它是如何工作的吗？

为什么不能在JTable中点击按钮
