What type of NSCell do you have set for the column (looks like you
only have a single column)? It is a specialized NSCell subclass that
knows how to display an instance NSHTTPCookie? If not this isn't going
to work as coded.
NSHTTPCookie isn't a string, number, image, etc. so one of the
standard cell subclasses wont know what to do with it. You either need
a custom cell subclass that can display it the way you want it
displayed or you will have to convert the NSHTTPCookie instance into a
form that a standard cell can handle (maybe an NSString).
