You could use customers.zipWithIndex.flatMap({ case (customer, index)
=> ... instead of customers.flatMap(customer => to get the index, and
then use index % 2 == 0 to see if it's an even row or an odd row. How
you get that style into your template is up to you -- using an
attribute bind param would probably be pretty easy, or emitting the
<td> straight out of the snippet.
If you need more guidance give a shout and I'll write you up some
example code.
Note that zipWithIndex only works on List, and it regenerates the
list, so if you have a bunch of customers on the page and are
concerned about performance you might want to do something different
(and less convenient).
