I think the OP means having two columns... one for nicks, one for text. I'm sure a DLL could probably accomplish this, and I'm sure you could even do a custom channel window that will do it. I'm not sure of any that do it, though.
If you just want to change the nick format to have a | after it, that's easy. Also, you can increase the indent so that it "appears" as though there are 2 columns, though it won't match the nick length exactly.
