I would use each_with_index if I were you.

Three suggestions:
The index is going to be somewhat arbitrary unless you get the
records in a well-defined order (i.e., put an :order => ‘column_a,
column_b’ option into your find). (Or use a named_scope or some class
method on your model rather than letting your controller do the work.)
If you want the current index to do something like zebra-striping
table rows, look at the cycle() helper method for your view.
Rather than “for a in @a”, you might want “@a.each do |a|” as James
