Change background color of column header of Crosstab

Hi,

I checked few posts online on Formatting Cross Tab.

Once such post is below.

What I noticed is I am not able to just change the background color of the column header.

This is my css script.

***************

.tab1 .sapzencrosstab-ColumnHeaderArea,

.tab1 .sapzencrosstab-HeaderCellAlternating,

.tab1 .sapzencrosstab-DimensionHeaderArea,

.tab1 .sapzencrosstab-HeaderCellDefault{

color: white; background-image: none !important; background-color: #F37121 !important;

}

.tab1 .sapzencrosstab-HeaderCellDefault {

background-color: #F37121 !important;

}

.tab1 .sapzencrosstab-DataCellAlternating,

.tab1 .sapzencrosstab-HeaderCellAlternating {

background-color: #ffffff!important;

}

**************

But it changes the color of Row header too which I dont want. Is this normal or am not using the right class which affects only the top header..

Any ideas?

Thanks

Arun
