Review comment:
I think the only way to make it work consistently would be to trim leading
and trailing spaces in the header names before adding to the table then doing
the same here would work. I can't imagine that there is a valid reason to have
leading or trailing spaces there but assuming that will mean that we might be
changing the actual data when coming from CSV files and the like. Thoughts?
