Tree Table with GoJS

I want to develop a tree table functionality with GoJS. Want to know if it is possible, if so any sample code is appreciated. Refer attached screenshot

Is each table supposed to be within a Node?

How is the tree structure represented? Is each row supposed to be a Node? If so the whole Node would have to be a Group.
An example of what I think you want: TreeView Filling Viewport
As usual, the complete source code is in the page itself.

This is exactly I am looking for. I don’t see a source code on the page, looks like its deployed application.

Could you please share the sample code?

ahem, as I said…
