NSTableView: column selection selects rows?

Hello,

I am implementing the following method in a subclass of NSTableView:

- (void)selectRowIndexes:(NSIndexSet *)indexes byExtendingSelection:
(BOOL)extend

The idea is to handle myself the selection / deselection of rows.

Unfortunately, this method also gets called when I select a column 
(to reorder). My table is connected to an array controller in a 
CoreData application.

Is there a way to either:

a) know when it is a column being selected
b) prevent rows being selected when I click on a column (actually, 
the method is called twice for each click on a column)

Thanks,

Alex
