设置为监听单元格选择事件的Jtable不会触发事件

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，如果我选择除选定单元格之外的其他行，Jtable引发事件。设置为监听单元格选择事件的Jtable不会触发事件

这是代码... 示例当我选择单元格“row0 col0”，然后尝试选择同一行中的任何其他单元格时，jtable将不会触发任何事件，以便触发事件“行0第1栏”细胞，我必须选择在第2行的任何细胞，并且具有点击“排0 COL1”细胞

请学习Java命名约定并严格遵守。 – kleopatra 2012-01-13 11:12:39

行和列选择由不同的选择模型来控制：

row：table.getSelectionModel（）
柱：table.getColumnModel（）getSelectionModel（）

你有你的听众注册到两个
