Hello, I'm finding all the answers I don't need to adjusting column width and I just don't know what else to search for. What I've got is 4 columns sized out to cover a page. The 2 outer columns, A and D, are small and fine where they are, but I don't want them to move or change. Columns B and C have a combined width of 539 pixels. What I'm trying to do is change to size of columns B and C without changing their combined width, in effect using columns A and D as immovable barriers. Is there an easy way to do this without manually changing B and C to equal 539 pixels each time I want to make a change?

Thanks.
