Counter

[Kim Armann <kim@nichols.de>]

Hi, I want to make a table with products like :
code   name     price
1      xyz1     12
2      abc      15
3      def      99
but i want a different bgcolor for line 1., 3., 5., ...  than for 2.,
4., ....
How can I make a "Counter" that I can use in an if-tag or something.

... THX, Kim Armann
