any way to hide a column (on-screen, not printout)

[Jon Sweet]

In the "OmniOutliner" config page of File->Page Setup..., I can  
specify any subset of the columns to printout.

Anyway I can do the same thing on-screen?

I don't want OmniOutliner to become a spreadsheet, but it's precisely  
because I'm trying to get away from using Excel (which has this  
facility) that I want it in OmniOutliner, which is the most  
shockingly useful app I've bought in months!
