java - Jtable as a Jtree Node

Question

I know you can create a table and add a JTree as a column. But what I want to do is the complete opposite.

Check the image and tell me if this is possible. Thanks!

UPDATE:

By using MKorbel's code and by randomizing the number of columns with the following code:

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

I was able to get the following image:

Answer 1

1) I didn't solve isLeaf() in Renderer and Editor somehow

2) if I put JScrollPane with JTable to the Node directly, (without using JPanel as parent) then JTree View isn't correctly rendered after start_up for more info please see my question Put JTable in the JTree
