We often want a column of decimals to have a percent sign only on the first
number in the column, so:
.553
.554
(.345)
need to be formatted to look like
55.3%
55.4
(34.5)
where all the decimals align vertically. I can't figure out how to do this
without multiplying the second and third cells by 100, which is a bad
solution.

Any ideas? Thanks.
