If you add all the columns (and remove old ones) before calling
setAutosaveName:, or setAutosaveTableColumns:, then it should work out
okay; it will restore all of the widths, positions, etc.

I'm working on an application that will allow users to add columns

In my test app, I can add columns to my table no problem. Now I am
trying to decide on a robust and efficient way to make sure that the
set of columns chosen by the user, and their geometry, is saved when
quitting the app and restored at the next launch.
I can think of a number of brute force ways to do it - save an array
of column identifiers and/or value bindings to user preferences, for
example.
I know it's possible to autosave column layout information under
Leopard through the framework, and this appears to work. The
autosave info appears to restore the geometry of columns defined in
the nib file, but it won't force a reload of columns created
programatically in the last session. I suspect that the autosave
file may actually contain the identifiers of all columns displayed
as of the last application quit, and wonder if there is a way,
during nib loading, to access this list so I can initialize the table.
I don't like having the same information stored multiple places
(i.e. my own NSArray in user prefs replicating info that might be
more complete in the NSTableView autosave file) if I can avoid it,
but can't seem to find a way to get at all the info in this file.
If anyone has some good examples of how this can be done, or some
past experience to share on what works well, I'd be very grateful.
