你需要做一些事情才能让它发挥作用。
There are a few things you need to get this to work.
首先看一下如何使用表获取更多de尾巴
Start by taking a look at How to use Tables for more details

要注意的关键领域是 AcceptRejectRenderer 和 AcceptRejectEditor ， setValueAt ，删除， isCellEditable MyTableModel 和 setCellRenderer 和 setCellEditor 构造函数中的方法....
The key areas to pay attention to are the AcceptRejectRenderer and AcceptRejectEditor, the setValueAt, remove, isCellEditable of the MyTableModel and the setCellRenderer and setCellEditor methods of in the constructor....
