推荐答案

DefaultCellEditor 对于许多 JTable 单元格类型委托给 JTextField ，它将 Delete 键绑定到 delete-next 行动。要抢占默认行为，您必须从 DefaultCellEditor 中删除​​现有绑定，如 如何使用键绑定：如何制作和删除键绑定 。您可以使用自己的绑定替换它，如示例所示; 此处显示典型的 DefaultCellEditor 。

The DefaultCellEditor for many JTable cell types delegates to a JTextField, which binds the Delete key to the delete-next action. To preempt the default behavior, you'll have to remove the existing binding from DefaultCellEditor, as shown in How to Use Key Bindings: How to Make and Remove Key Bindings. You can replace it with your own binding, as shown in this example; a typical DefaultCellEditor is shown here.
