I need to have the maximum value in a column replaced with it's ocncordant
label.

For example in the following table I need to see Alberta rather than the MAX
value underneath the Jan Column:

Sales by Region

Manitoba 45600 44000 48000 48000 46500
Ontario 45650 49000 56000 64500 58700
Saskatchewan 45900 45000 45600 44100 38900
Alberta 55700 48000 51000 54500 54600
