No, the basic building block in OmniOutliner is an entire row spanning all of the columns. If you sort one column, the others move as well. One could write an AppleScript for the Mac version to move individual cells around as you propose, but that doesn't help you if you've only got the iPad version (and this should not be construed as an offer to write said script, just an opinion that it is feasible). You could of course do your manipulation via cut/copy and paste, though it might get a bit tedious...

I wonder if a spreadsheet might be a better fit for this task?
