Where can I find some documentation/example out there that shows how to map an unknown/variable number of columns to a NSTableView?

It's very easy. Just create it in code. Each column in an NSTableView is represented by an NSTableColumn object. Just create it using alloc/init, add it to your table. If you're using alternating row colors, you may have to fiddle with the data cell a little (I think you need to use an NSTextFieldCell and set it to not draw its background), but that's as complicated as it gets.

A quick read of the headers should get you all the method names you need. Though you may want to use Key-Value-Coding based on the column identifier (which you of course would have to set) to allow yourself to generically access all your columns' data with the same code from your data source.

But there are no hidden pitfalls, I've successfully done it for an SQLite table.
