A (very!) minor point: You have to implement *one* protocol,
NSTableDataSource, which consists of these two methods.
- (int)numberOfRowsInTableView:(NSTableView *)aTableView{}
- (id)tableView:(NSTableView *)aTableView
objectValueForTableColumn:(NSTableColumn *)aTableColumn
row:(int)rowIndex{}
1) How to populate in the simplest way the table?
The table will populate itself by calling the second method as needed.
2) Must I transform the return query values to an NSMutableArray?
No, you can store them however best suits your app. Note, however, that
you must be able to quickly retrieve them given an integer index -
usually, the best way to do that is to fetch them from some sort of
array.
3) When and how must I redraw the TableView?
You don't. The TableView knows what rows are visible and need to be
redrawn, and it will call the second method above as needed, and redraw
itself.
