Jtable作为Jtree节点

我知道你可以创建一个表并添加一个JTree作为列 。 但我想要做的就是完全相反。

检查图像并告诉我是否可以。 谢谢！

更新：

通过使用MKorbel的代码并使用以下代码随机化列数：

@Override public int getColumnCount() { int i = (int) (Math.random( )* 10.0); if (i%2 ==0) return 2; else return 3; } 

我能够得到以下图像：

Answer 1

1）我没有在Renderer和Editor以某种方式解决isLeaf()问题

2）如果我将带有JTable JScrollPane直接放到Node （不使用JPanel作为parent ），那么在start_up之后JTree View没有正确呈现以获取更多信息请参阅我的问题在JTree中放置JTable
