Crosstab with 3 different rowcolors

Hi all,

in one of our dashboards i have a requirement to style a table with 3 different rowcolors, as u can see in the screenshot below.

I tried to achieve this by setting up an alternating table with blue and orange the way it is described here in SCN (worked fine).

To change the color of the 3rd row i tried to use css-selectors directly on the tables like:

#CROSSTAB_1rowHeader tr:nth-child(3){

     background-Color: grey;

}

But the color of the 3rd row is not changing..

any idea?

Thank you!

Regards Kai
