Hi,
I'm writing a program that ranks the winner of an election using ranked pairs. I was wondering if it was possible to sort columns. the margin column in table2 needs to be sorted from largest number to smallest number. I've tried TableRowSorter but as expected that has not done anything. Is there anything else I can use?
