Coloring best per column in crosstable

Hi All,

Hope you could help me with this. I have a cross table with several (9) columns. In every column are results of some selling period. I want to know the best value in each column. I want to archieve this with coloring, but if I try to color the cross table and choose for new rue > Top 1, only 1 value is colored. 

What can I do to color best value per colomn?
