I don't think t:columns has significantly changed since 1.1.1.

I also don't see any problems with what you proposed.  It should work
if you have a list of column objects as part of each and every row

No, this is different.   This is a list of row objects, an independent
list of column objects, and a data model that represents the
intersection between the two.

In this model, there are n rows and m column objects.   In your model,
there are n rows, and nxm column objects.
