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:

I haven't tested it, but why shouldn't this be possible. The API requests that the renderer returns a component. And a JTable is a component. Editing/selecting in the JTable might be more difficult – Shiloh

@Shiloh But I mean visually, is it appropriate? Does it present any difficulties? – Manchu

Now this is interesting. My 2 cents: I just feel like visually if your tables are big, your tree might look kind of funky. Also, I am curious about whether or not you will actually be able to interact with the table. Would it be just an image of the table? – Cheremkhovo

@Cheremkhovo Well in my case, I just use it as a readOnly. but it would interesting to make it editable, ... – Manchu

this JTree with JTable in the Node look like very similair as in your picture, put there JPanel --> JScrollPane --> JTable, is JTree will be editable, then you can to edit Cell in the JTable too, +1 nice question – Chimp

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

Thank you for your code. I modified it a bit to obtain the Updated result in my question. I was just wondering if what I modified with the best way to do it? – Manchu

But the Table is not editable.How to edit the contents of the table – Help
