You'll be able to get better help if you can describe your problem in
more detail, including what you tried (source code), what it did, and
what you expected it to do.
You've basically said, "It's broken," which isn't a whole lot to go on.
I see in a later email that you've read, or at least have looked at,
the Agile book. Modifying your views is covered pretty well in there,
which leads me to believe that you're running into a Ruby problem
rather than something specific to Rails. Displaying a column, or not,
should be trivial assuming you know some basic Ruby.
Again, you haven't really provided enough detail to give a good answer.
