How to expand the number of columns in a worksheet

[Ying Barlow]

Does anybody know if it's possible to expand the number of
columns in a worksheet (only up to "IV" in default), if it
is, how? I need to display a matrix of 400x400 in a
worksheet.

Thanks in advance.

Ying,

256 columns is the limit.
There isn't any way to override it.

If you need to do anything numerically nontrivial with this matrix, you
shouldn't be using Excel. If you're *only* displaying it, you could use a
monospaced typeface and combine several space-separated entries into each
column.
