How do I Sort data vertically not horizontally in smarty?

I have 3 columns and my information is being displayed correctly. However,
the information is being displayed horizontally.
1 2 3
4 5 6
7 8 9
How can I display it vertically instead?
Like this:
1 4 7
2 5 8
3 6 9
{foreach from=$cat.SUBCATS item=scat name=scategs key=key}
{capture name="column"}{math equation="x % 3" x=$key}{/capture}
{if $smarty.capture.column == "0"}
(table info here)
