Change orientation of rows and columns of Vaadin Grid

Question

How do I rotate or change orientation of rows and columns in the new Grid widget in Vaadin 7?

My requirements are such that I need to change both. a) header-rows and b) cells content. In this image, there are twelve columns (1-12) and eight rows (A-H), so I've to change the orientation of twelve columns into eight rows and eight rows into twelve columns and all its cell content as well.

Answer 1

It seems that Vaadin 7 does not have such feature implemented in new Grid. However, one can manually rotate the items within container to change orientation.
