Per documentation "output" graphic in image attached, using row-span aligns the text A across multiple rows.

B C
A
D E

Can the A text be vertically aligned with the top? So....

A B C
D E

I want to do this so boxes around the columns each have text at the top.

You can apply "vertical-align: top" to the table cell.
