-tabsplit- restructures the dataset temporarily to do what it does.
The tabulation uses -tabulate-, but the original data structure is
restored. That's deliberate. If you want something else, you are free
to clone the program and rewrite it accordingly.But this is the same
question as the next really, so see below.

You want a -stack- or -reshape-. Advice at length was given in the
references I gave earlier, so I have to guess you haven't read them.
