Hi,
Since no one else seemed interested and I needed to get HTML table
column widths into a PDF file, here's a patch for a simple
implementation (attached).
Only percentage values are supported and they are relative to each other
(so two columns set to "1%" and "4%" are actually 25% and 75% of table
width).
Table cell (TD) widths are retained from only one row (TR), i.e. the
last one that has a width set, and those widths are only used if they
are set for all the columns. Nested tables work as expected.
As said, it's limited but at least now there's an option.
