I am trying to align my columns by decimal point. I have both negative and
positive numbers, as well as asterisks (to show statistical significance) and
so using Format|Cells|Number and trying the number, currency, and accounting
options don't seem to work, nor does the custom option when I try ##.???? or
-#.????.

For example, I have the following numbers I want to line up:
-0.2684***
-0.2602***
0.7165**
1.0023

Any suggestions?
