将jRadioButton添加到jTable中

将jRadioButton添加到jTable中

1. 如果要编辑表格单元格的值，则必须设置一个

   TableCellEditor

   。
2. 您应该

   JRadioButton

   在渲染器中创建一个单一文件，并在任何地方重复使用，这就是TableCellRenderer的目的。
3. 如果您不打电话

   super.getTableCellRendererComponent

   ，则不需要扩展

   DefaultTableCellRenderer

   ，只需执行即可

   TableCellRenderer

   。

考虑阅读JTable教程，以更好地理解渲染器和编辑器的概念。

这是有关如何进行此工作的示例。当然，您必须适应您的模型，但是您应该了解要点：
