问题
There has been a question to a specific kind of grid:
The question has already been answered but the questioner also asked if this kind of diagram has a formal name which is what I'm interested in and the accepted answer doesn't include such information.
Is there any simple way to achieve something like this in GWT/GXT (apart from drawing the two lists and these lines manually)?
