Re: xsl, FOP warnings and errors messages on console

Can you give one example of this please ?

Either use an absolute width for each column:
 <fo:table table-layout="fixed">
   <fo:table-column column-width="3cm"/>
   <fo:table-column column-width="3in"/>
   <fo:table-column column-width="36pt"/>
   <fo:table-body ...
or specify a width for the whole table:
 <fo:table width="100%" ...
or
 <fo:table width="10cm" ...
In both the latter cases you must still specify a width for
each column, but you can use the proportional-column-width()
function:
 <fo:table width="100%" table-layout="fixed">
   <fo:table-column column-width="3cm"/>
   <fo:table-column column-width="3in+proportional-column-width(1)"/>
   <fo:table-column column-width="proportional-column-width(2)"/>
   <fo:table-body ...
FOP does not support percentages in column width expressions.

This is processor specific and should better have been asked
on the FOP user list.
