[stringtemplate-interest] How to fill a <table> grid wise?

[John Snyders]

I think the easiest thing to do is change the program generating the data to create a list of lists. 

In JSON format the data would look like this
{"mat": [ [ 0, 1, 2], [3, 4, 5], [6, 7, 8] ]
}

Here are the templates to process it:
group matrix;

main() ::= <<
  $table(t=mat)$
>>
table(t) ::= <<
  <table>
    $t:{<tr>
      $row(it)$
      </tr>}$
  </table>
>>
row(r) ::= <<
 $r:{<td>$it$</td>}$
>>
