yes that (because I store the list of pending spans in a string, and
pull of each one using substring, if you need more, you could use
a delimiter and substring-before to pull apart the string, that's easy
to change once the rest of the logic is right.

Also there's a xsl:message that terminates if the column count gets
above 10, that isn't a real restriction it's just there as your examples
only had four columns, but some versions of the code didn't terminate
the recursion without that trap.

details details...

I just posted this to Oliver who also pointed out that it didn't work off
the list (I suspect not because he's scared of correcting me in public,
having done that often enough, but that it would be his turn next if it
transpired my attempt didn't work)

yes that's due to a last minute addition:-)

I noticed that in Norm's last example he didn't want his rows to end early

<table border="1">
<td rowspan="3">A</td>
<td class="auto-generated"></td><<<<<<<
<td class="auto-generated"></td>
<td class="auto-generated"></td>

so I added the bit at the end marked

   <xsl:for-each select="/descendant::*[position() &lt; string-length($spans)]">
  extra cell
<td class="auto-generated">.</td>

but that's wrong, it shouldn't just generate those, it should force the
loop to continue until $spans is empty, so it correctly catches cells
hanging down from above.

(something for Norm to do, he's probably up by now:-)

You don't deflect a true believer that easily:-)
