How can I change the row heights and column widths such that the cells are
exactly square? It appears the numbers we enter in the row height and column
width popups are not in the same units.

Moreover, if there is a way to specify the dimensions of the cells such that
they will be a specified size on the printed page, say in easy to define
units like 1 inch by 1 inch, that would be really helpful.

Your help greatly appreciated.
