Create enum for columns

[markcrivera]

          This looks like you're trying to handroll an enum.  Enums under the hood are integer indexed I believe, so you could just make an enum for this and grab the values that way.

Don't forget that enums are PascalCase for both their own name as well as the items defined in them.
