Yes, sorry, forget what I said about the dquotes. I mixed things up with the j(ava)script I do elsewhere currently. The column.method property expects a string with a function name of course, not a reference to a function (which would be just the name of the function without the dquotes).
There error is somehwere else and it is not in the way you assign functions for the columns. It's in the column functions, as they always set both columns. That's why you cannot have one column showing units, while the other is set to auto.
I removed some of the duplicate code which served both columns at the same time.
The column function now only act on one column at a time, so using different methods for each makes sense eventually.

While I tinkered with that script I was also able to reproduce a script column bug I saw with another script. So if the uploaded fix works for you, I guess we have a win win situation here. o)
