You can also transform it into a more general problem:

Combine n arrays in an item-by-item way

To do so, we just push all the arrays in a $AoA, and use boo_radley's transpose AoA and HTML table AoA contents. to transpose that $AoA, and take a simple map join( '-', @$_), @$_; to join the elements. Works for arbitrary n.
