你需要both一个渲染器和和编辑器，如下图所示示例.请参阅如何使用表:编辑器和渲染器，了解详情.切线地，您应该覆盖 TableModel 中的方法 isCellEditable() 而不是扩展 JTable.

You need both a renderer and and editor, as shown in this example. See How to Use Tables: Editors and Renderers for details. Tangentially, you should override the method isCellEditable() in your TableModel rather than extending JTable.
