Rather, a cell view is resized, just after being instantiated, for the row height of the row it was created for. Note that this means that the run-time height of each row must be known in advance of creating the cell view for the row.

For the simplest case, this matches the run-time row height, but this isn't necessarily so (if you programmatically change the row height, or if you're going to use a variable row height).

There's a setting for "Automatic"…where does it get it from then?
Also, is there no way, using bindings, and no delegate, to choose among multiple NSTableViewCell implementations? I thought the 2011 WWDC video said it was possible, but I didn't quite understand what it was referring to. Unfortunately, there's no straightforward pure-bindings example to look at.
