Horizontal/Vertical spans

I'm trying to get horizontal and vertical spans working within a <table> (note en/reference/strings/functions/nl-langinfo.xml). See http://docs.php.net/?q=function.nl-langinfo for the current copy. The "LC_* Category" cells should span both columns but as you can see, they do not. I tried <spanspec> and setting namest and nameend in the specific <entry> (along with the <colspec> giving symbolic names to the columns) but neither of those worked. I was wondering if anyone else had any suggestions. Also, am trying to get a vertical span (a cell spanning 2 rows). I tried morerows="1" but that also did not work. Any suggestions on that would also be greatly appreciated. Thanks, Kenneth
