Thank you for your response,
Yes I am talking about reporting, I have to do somthing like a table with a simple columns, and I want being able to change the color of my columns(just in the header of my table) each time I want.
I can give you an exampl:
I have my table with 4 columns, "ProdID",Price","Quantity", and"summe"
and I want to color these 4 cellules (which are the header of my table) with the same color, and be able to change it as I like.
do you inderstand me???
