当我们从同一行中选择时，设置为监听单元格选择事件的 JTable 不会生成事件，如果我选择除所选单元格以外的其他行，Jtable 会触发事件。
这是代码... 例如，当我选择单元格“row0 col0”，然后尝试选择同一行中的任何其他单元格时，jtable 不会触发任何事件， 为了触发“第 0 列第 1 行”单元格上的事件，我必须选择第 2 行中的任何单元格，并且必须单击“第 0 列第 1 列”单元格

最佳答案
行列选择由不同的选择模型控制:
- 行:table.getSelectionModel()
- 列:table.getColumnModel().getSelectionModel()
你必须同时注册你的监听器
