I'm glad it helped you out! And you are right to give it some more thorough tests, as my tests focused on my use and not on all possible fields to display.
Taking a quick glance at the code, I see that I set the width of the columns to 99%, as an addition to the style class in CSS. I guess that made it fit. A bit of a workaround, but nevertheless it works :-)
The horizontal line was easy to fit in, as eventually, in the new code, the page is processed top to bottom. For the record: line 260 contains the <hr>.

I'll be happy to hear if you find any issues.
