问题是JTable中行的高度是固定，所以这不仅仅是渲染渲染器的问题;我不确定它为什么没有，但如果确实如此，那么包装好的文字会被裁剪掉 - 或许这正是你所看到的。要调整行高，您需要单独设置它们。

The problem is that the height of rows in JTable is fixed, so it's not just a matter of having a renderer that wraps; I'm not sure why it doesn't, but if it did, the wrapped text would be cropped - or maybe that's exactly what you're seeing. To adjust row heights, you need to set them individually.
