So you want your data to look like this?
Name1 Name2 Name3
Name4 Name5 Name6
One option is to create a nested loop and send that data structure to
the code. It will look like this:
$names = [
{
row => [
{name => name1},
{name => name2},
{name => name3},
],
},
{
row => [
{name => name3},
{name => name4},
{name => name5},
],
},
];

Alternatively, you could try the HTML::Template::Expr module (which I
have never used). It should allow you to express logic like:
"After after third table cell, end the current row and start a new one".
(Hint: use the modulo operator: "%").
