macOS Showing serial nos. in a table column using NSArrayController and cocoa bindings

[Monaj]

Hi all,

I have a simple question:

How to show serial nos. or (row no. + 1) in a table column using cocoa bindings and array controller?

have made an application using cocoa bindings and array controller, in which I am displaying names of certain persons in a table column. The class from which I am displaying is named as: Person. Now I want to show serial nos. in first column, such that list gets displayed like this :

1 / John

2 / Peter

It is very easy to do if I use data source method:

- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex

I just need to return something like this :

return [NSString stringWithFormat:@"%d",rowIndex+1];

but I am not getting how to do this via cocoa binding and array controller.

Can anyone suggest me solution for it?

Thanks,

Monaj
