Well, you just dont want to do this in TAL, really ;)
You have to choices: either not using a table but
a couple of carefully CSS-crafted <div> tags
(See alistapart.com or so for hints on tableless floating
designs)

Or you go the easy path and have a data preparing script
(Script (Python) - Object) which does something along the lines
of:

data=your_nine_items

rowlength=2

return [data[i:i+rowlength] for i in range(0,len(data),rowlength)]


I think you get the idea :-)
