For intra-table view dragging only, you can just stick the row indices
onto the pasteboard like this:

- (BOOL)tableView:(NSTableView *)tableView writeRows:(NSArray*)rows
toPasteboard:(NSPasteboard*)pboard {
[pboard declareTypes:[NSArray arrayWithObject:NSStringPboardType]
owner:nil];
[pboard setPropertyList:rows forType:NSStringPboardType];
return YES;
}

Extract in the acceptDrop with [[info draggingPasteboard]
propertyListForType:NSStringPboardType].
