You'd need a custom renderer that does the
multicolumn layout.
I've attached a function that takes a list of items
and returns a list of lists. I created it for the
purpose you describe. It's not the prettiest or
most elegant code I've written, but I wrote it
when I was learning Python; since it works, and
I don't need it often, I haven't bothered trying
to improve it.
I added a couple of simple examples to the docstring.
Hope this helps.

If all you really want to do is have the names and ages displayed next
to each other, why not use ordinary nevow:render="sequence" along with
CSS? A demonstration of the stylesheet you'll need is at
<http://tw.ecritters.biz/html_examples/tile/>.
Thanks for this hint, it solve 50% of my needs ...
There is one reason, why I'd like prefer the <table> solution:
the variable column width!
In real, I'd like to use this for database field editing and the variable
field width get very important.
But your way is better than no way !!!
