Issue changing background color header in crosstab

Hi guys,

I have a crosstab and I'm trying to change the background color at dimension header level and column header level for specific dimensions and columns, using CSS script.

For example, I want to change the dimension header background color for the 2nd dimension with the following CSS script:

.sapzencrosstab-DimensionHeaderArea tr td:nth-child(2) { background: #A52A2A !important }

The problem is the icon for sorting is painted too and I don't want that.

Please, any idea how to solve this?

Thanks in avance!

Andrea.
