Auto Hide Columns when...
 

I have a spreadsheet that has monthly columns. Each new month I need to show
the stats for that month as well as a column for the ytd. But, I don't want
a lot of ytd columns printing. Ideally I would like to keep the individual
monthly YTD stats available should I need them.
Example: Jan Feb Mar YTD
5 5 5 15

Jan Feb Mar Apr YTD
5 5 5 5 20
