I'm workig with this, and i change the SAXiTextHandler.java on the "ROW"
area (see below between the //DANY are my change to support relative
width)
I'm change this when i use the HTMLParser but, now i'm need stylesheet and
i use the HTMLWorker, the table are some problems yet. I'm working on
that.
Hope this help.

Add html attributes: wrap the iText objects in a MarkedContent object.
Set relative widths: inspect the HtmlWriter code. I don't know the
answer by heart; it's as much work for me as it is for you to check
the code; so I'd rather have you doing it ;-)
