Number formatters in tables on GORM

[Graham Lee]

Hi folks,

I have an NSTableView, and want to attach an NSNumberFormatter to one of 
the columns. What I _think_ I should do is drag the number formatter 
avatar from the Gorm palette to the column, but that has no effect.

Specifically, dragging the formatter onto most of the table's area shows 
the "no entry" cursor. If I drag it over the column headers, the cursor 
changes to the source/target overlapping rectangles, but dropping the 
formatter has no visible effect, and the document is not dirty (i.e. no 
changes were made).

There's a workaround, in that I can do all this in code, but can I avoid 
that by using Gorm? Am I just holding it wrong?

Thanks for your help,

Graham.
