Is there an easy way to set the widths of rows and columns to be the same?

This question came in by e-mail.

To set a range of rows or columns to the same width:

a) Highlight (select) the rows and columns you want to change using left shift-click or ctrl-click to choose non-contiguous rows and columns.

b) Adjust the width of one row or column using your mouse. All the selected rows will be changed to the same width.

Voila!
