Change background of 'Category' titles.

[Outsider]

I noticed that most of the themes display categories with albums differently then categories without albums (or more sub-categorries)
Eg: http://www.onsendesigns.com/cpg132
This is my site, and looking at the first 3 categories, and the last 2 categories, the text background has horisontal gray lines running in the background of the top three.
What I want is for that effect to be present in ALL categories.

What makes that change?

Thank you.

In the theme's style.css file copy the attributes from tableh2 to tableb

Thank you... That worked wonderfully!
