但是它还没有使我能够检测到这个单元格的旧值和新值。我还需要做什么？

But it doesn't yet enable me to detect the old and the new value of this cell. What else do I have to do?

使用TableModelListener监听更改更容易，但仍然有问题可以访问旧的值。

It is easier to use a TableModelListener to listen for changes but it still has the problem of not being able to access the old value.

查看表格单元格侦听器，为您提供访问旧值以及新值的解决方案。

Check out the Table Cell Listener for a solution that gives you access to the "old value" as well as the "new value".
