I put the full headings back in. It's 9 days old now, so probably won't be viewed much between now and whenever you get the new version published. The scrolling looks nice on your test site. Thanks for updating that.

Great, thank you. That saves me trying to find another table!

It works well on a mobile - definitely a big improvement for a few lines of CSS!

Yeah, I did that in an edit to reduce the width of the columns so that the whole table would be viewable.
