具有JSpinner的JTable启用/禁用

我有一个3列的JTable.第2列是一个复选框，我想为该行启用/禁用JSpinner.

I've got a 3 column JTable. Column 2 is a checkbox which I want to enable/disable the JSpinner for that row.

除了一件事之外，我已经按照自己的方式工作了-JSpinner实际上看起来并不像它的已禁用(文本和微调按钮为灰色).我不太确定如何实现这一目标.我已经尝试过在JSpinner上强行调用setEnabled(false)，但是该表似乎无法正确重绘.

I've got working how I want except for one thing -- The JSpinner doesn't actually look like its disabled (text and spinner buttons greyed out). I'm not quite sure how to attain this. I've tried forcibly calling setEnabled(false) on the JSpinner, but the table doesn't seem to redraw correctly.

以下是我通过其他StackOverflow示例工作的一些代码:
