Very neat, but I think the sorting goes wrong in case a table cell has spaces. Concretely, there's an issue with table entries of the form "05h 59min 57.00s", which should be sorted alphabetically, I assume, but it turns out they are not. The issue is gone, though, once the spaces are removed.

I'd really appreciate an update, it's a 5/5 except for that very annoying issue!
