A pretty rare requirement maybe, but some data structures (I have one) might be more suited to being displayed that way e.g. when there are many "columns" with lengthy titles and it would be easier on the user not to have to do lengthy horizontally scrolling. Yes, in such a case one could hand code a table or something - but it would be nicer to have all the styles and controls of the grid..
Perhaps Alex can come up with a "setPivot(true)" method (...or have i missed this...)?!!
Yes, I know you'll being saying I want it to make coffee next......
Anyway, just a thought.
