I'm trying to obtain a table where you can collapse rows using a + or whatever symbol, like in this image from Access:
Actually, I would like to have the same behaviour, with the title of the columns like that. I will use only 2 levels: the one that have the + and the ones that do not have (different parents with different childs but childs won't be parents). At the moment I am trying Jtable inside Jtree but I'm quite far from the objective and the results are not near... I cannot edit table cells neither I can have the column names like this case (If I put the title of columns each parent will have the title). Do you know some java swing component with a behaviour like the one that I want to obtain or some code that could do this? Any help with the code I wrote?

For those looking for something similar, I found this:

If you want to use swingX, every link I found was broken (java.net does not exist anymore) and I couldn't find an official repository. But still, you can find the last upload from the SwingX project at several github personal projects who had replicated it like this one:
