Hello everyone,
I've been doing a little test using the following xsl-fo. Everything
works fine except when I suppress all the column-width="..." in the
first table then FOP doesn't give any warnings and the second table
simply disappears. I'm not sure why this is happening.

Uh, no. I just wanted to point out that "auto" is not a valid value for
column-width. What you probably meant was the case when the user doesn't
specify the column-width property in which case the value is not "auto"
but "proportional-column-width(1)" (see FOPropertyMapping). If that's
correct and usable remains to be seen.

Thank you for the advice.
I will sum this up on the wiki page.
So if I understand correctly we have to support certain values even if
they are illegal ?

Right, but strictly speaking the value "auto" is illegal for
column-width. FOP currently defaults to "proportional-column-width(1)"
if no value is specified.
Another thing we should be careful about is the distinction between the
value set for table-layout and the effective algorithm to be used. If
you specify table-layout="fixed" but without an ipd, the rules for
automatic table layout are activated.

Hi Patrick,
My first question, really simple but confusing to me, is about what is
supposed to happen when table-layout="fixed" and one of the columns
has
column-width="auto" ? Am I supposed to find out the optimal width
juste for
that column ?
Yes, but with one big difference compared to table-layout="auto".
IIRC, CSS mentions this case explicitly: when table-layout="fixed"
and column-width="auto" then the column-widths are ultimately the
widths necessary for the cells in the first row. No need to look at
the whole table, in any case...
