Hmm... an untested suggestion... <table> $cells:{ row | <tr>$row:{ cell | <td>$cell$</td>}$</tr>}$ </table> (i.e. nested iteration) or to encompass the table call inside, $cells:{ row | <tr>$row:{ cell | <td>$cell$</td>}$</tr>}:{<table>$it$</table>}$ Regards, Sterl.

I am trying to use HStringTemplate for generating html tables, for use in http://happstutorial.com:5001
The best I could do is below. Seems awfully kludgy.
Can someone suggest a better way, which keeps me inside the StringTemplate way of doing things? (Eg, no suggestions to use HTML.* libraries, which are nice for some things but are a higher barrier to entry than just jumping in and writing html.)
Some kind of map structure... for each... ?
Thanks for any help!
