我已将单选按钮添加到JTable使用的渲染器和编辑器。我也创建了相同的组。我无法使用此原理实现排他性（只能选择1个单选按钮）。请在下面查看我的代码，并感谢你的答复。
渲染器和编辑器类：
class RadioButtonRenderer implements TableCellRenderer { public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if (value == null) return null; return (Component) value; } } class RadioButtonEditor extends DefaultCellEditor implements ItemListener { private JRadioButton button; public RadioButtonEditor(JCheckBox checkBox) { super(checkBox); } public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) { if (value == null) return null; button = (JRadioButton) value; button.addItemListener(this); return (Component) value; } public Object getCellEditorValue() { button.removeItemListener(this); return button; } public void itemStateChanged(ItemEvent e) { super.fireEditingStopped(); } }
这是准备数据并完成分组的地方：
private void displayPhoneListShow(Person person) { DefaultTableModel dm = new DefaultTableModel() { @Override public boolean isCellEditable(int row, int column) { return true; } }; Object[] objects = new Object[3]; Object[] tableColumnNamesPhone = new Object[3]; tableColumnNamesPhone[0] = "Select"; tableColumnNamesPhone[1] = "Phone Number"; tableColumnNamesPhone[2] = "Preferred"; dm.setColumnIdentifiers(tableColumnNamesPhone); ListIterator<Phone> phoneList = person.getPhoneList().listIterator(); while (phoneList.hasNext()) { Phone phone = phoneList.next(); objects[0] = new JRadioButton(("^")); objects[1] = phone.getPhoneNumber(); objects[2] = phone.getPreferred(); dm.addRow(objects); } this.phoneTable.setModel(dm); ButtonGroup group = new ButtonGroup(); for (int row = 0; row < dm.getRowCount(); row++) { JRadioButton radio = (JRadioButton) dm.getValueAt(row, 0); group.add(radio); } phoneTable.getColumn("Select").setCellRenderer( new RadioButtonRenderer()); phoneTable.getColumn("Select").setCellEditor( new RadioButtonEditor(new JCheckBox())); }
我仍然无法取得结果。我也尝试过添加ButtonGroup group = new ButtonGroup()作为类变量以及类的一部分，RadioButtonRenderer并向该组添加按钮。但是结果并不重要。
ButtonGroup group = new ButtonGroup()
RadioButtonRenderer
请提出建议。
