Organise multiple columns numerically

Hi

I have data in the following format over 200 columns:

Product 1 Product 2 Product 3 Product 4 Product 5
Customer 1 4 0 0 8 1
Customer 2 5 0 0 7 1
Customer 3 9 0 0 4 2
Customer 4 4 1 0 1 3
Customer 5 1 4 0 1 0
Customer 6 1 4 1 4 3
Customer 7 2 0 0 8 2
Customer 8 0 7 0 3 1

Total 26 16 1 36 13

I'd like to be able to sort these columns so that the largest value product appears on the left descending to the right.

Is this possible?

Thanks

Steve
