You need to restart the webservice to apply changes in gluon

Current html2pdf conversion will not work properly if you don't use
explicit widths for table cells.
You can see the supported tags and a working example here:
http://code.google.com/p/pyfpdf/wiki/WriteHTML
Actually, I'm working in a better html2pdf render, using helpers and
web2pyHTMLParser:
http://code.google.com/p/pyfpdf/source/browse/fpdf/html.py
Hopefully, web2py helpers will improve the rendering mechanisms
