Make use of the parameter row and column passed to

- (void)browser:(NSBrowser *)sender willDisplayCell:(id)cell
atRow:(int)row column:(int)column

Moreover you need to return a differnet number of rows for the given
column in

- (int)browser:(NSBrowser *)sender numberOfRowsInColumn:(int)column

e.g.

if (column == 0)
   return [snippetObject count];
else if (column == 1)
   return [snippetObject itemAtIndex: column] numberOfLeaves];
else return 0;

And make use of [cell setLeaf:NO]; in

- (void)browser:(NSBrowser *)sender willDisplayCell:(id)cell
atRow:(int)row column:(int)column
