You can't - column width applies to the column, not individual cells.


You could make column A's column width 4, column B's column width 16,
and merge the A and B cells in row 1 through 10.

However, I don't recommend this as merged cells are the spawn of Satan,
and can make formatting, selections, etc. a real PITA. Just my personal
opinion, of course.

In rows 11 through 20, I want my column width to be "4"

How do I do this ?

Thanks
