Sorry, only percentage is supported.
Pt and Em and any other unit is not supported.
I'll try to add better error messages and documentation, sorry for the issue.

Sorry, but definitively your report is out of scope of html2pdf /
pyfpdf right now.
Please remember, the current implementation is a basic HTML parser to
do *basic* reports.
Nested tables are not supported and I don't think they will in the near future.
If I could get some funding maybe I could spend more time enhancing this.

AFAIK Reportlab doesn't even have a html2pdf conversor.
If you switch to reportlab, you will have to code your report using PlatyPlus.
You should consider they commercial licence that includes paid support
for this kind of issues.
As you said, the html2pdf recipe is a simple web2py project
Maybe you have to go with third-party tools like Pisa (xhtml2pdf) or
use built-in pdf conversion of chrome-browser, or pdf printers.
