"only those colums which has values"

it is not possible to pre-determine which columns to select until after the entire table has been scanned for values in each column

for example, suppose the table had the following values --

A B C D E F
1 4 2 0 1 0
3 5 6 0 5 0
6 6 5 0 4 0
9 0 2 1 0 0
0 4 9 0 3 1

now every column has a value!!
