There are two ways to give more information to your custom cell: - Use an NSDictionary or an instance of a custom class as your object value. If you're using a data source, return this object in your objectValueForTableColumn method. If you're using bindings, bind the array to a key path which produces this object. In both cases, this dictionary or custom object will be passed to your cell's -setObjectValue: method, and then you can do whatever you want with its contents. - Implement the willDisplayCell delegate method. This method is called just before the cell is displayed, and at that point you can do whatever you want to it based on the column/row information provided. Depending on exactly what you need, you may not even need to implement an NSCell subclass if you use this approach, if you can customize NSButtonCell sufficiently.
