For reference,
What I needed was :
1)- (void)tableView:(NSTableView *)aTableView willDisplayCell:(id)aCell
forTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex
in fact its NSOutlineView equivalent:
- (void)outlineView:(NSOutlineView *)outlineView
willDisplayCell:(id)cell forTableColumn:(NSTableColumn *)tableColumn
item:(id)item
(thanks John)
2) Tell the data cell to draw its background, and set its color
[cell setDrawsBackground: YES];
[cell setBackgroundColor:[NSColor orangeColor]];
(thanks Stiphane)
3) Remove intercell white space (between columns):
[outlineView setIntercellSpacing:NSMakeSize(0, 1)];

To save storage, NSTableView reuses cells to draw multiple items.
