Template Feature
 

There is an excel template available from the microsoft office at
http://office.microsoft.com/en-us/te...CT101172321033

This download template has a feature on it (above row A) that allows
expansion and collapse of hidden columns using '+' and '-' buttons. Can
anyone please enlighten me as to what this feature is referred to and the
process used to create and eliminate this in other spreadsheets?

Many thanks
