Hiding last column of a crosstab

Dear Experts,

I am using SAP design studio 1.6 with BEx queries as a data source .

I have a crosstab like this.

I don’t want to display the last column i.e. Column C and want the output like this

I’ve used this formula but it’s not hiding the required one

.x .sapzencrosstab-ColumnHeaderArea td.sapzencrosstab-HeaderCellDefault:not(:nth-child(2)),.x .sapzencrosstab-DataArea td.sapzencrosstab-HeaderCellDefault:not(:nth-child(2)){

display:none!important;

}

Thanks for your help!!!
