How to theme tables in Corolla

Hi folks,

I'm not clear with the css in Corolla.

I want to change the table styles for some blocks (padding/margin for tr). For testing I changed background-color and color and this tests were ok. (I used green and red and it's ugly;) )

In the same class I wrote padding and margin with px. Firebug shows me that it sees the changes, but calculates still with margin/padding 0 although I wrote other values!???

So without knowing the concept of reset.css I commented the settings for margin out!? But nothing changes.

In the documentation of css for Corolla it links to Adaptive Theme, which is proper for Corolla Version 7.
But I don't see any explanation for version 6.

Can anybody please describe how to change?

Thx in advance,

maen
