With that kind of table you shouldn’t get any warning. Are you sure that
/every/ table in the FO output is specified like this? For instance,
headers and footers are laid out using tables. Maybe column-width is not
specified for those ones.

What version of the XSLT stylesheets are you using? This problem
shouldn’t appear with recent versions (I tried with version 1.73.2).
Also, setting the fop1.extensions customization parameter to 1 might
help.

This shouldn’t be necessary, proportional-column-width is fully
supported.
