John,
I guess I forgot to send an e-mail saying Andrew Merenbach helped me
out on this one. He found a small error in my code. :)

OK. Now with connecting it in IB it stills seems to be not working.
I have made those changes that you said and nick also stated. :)
But I am still getting a blank NSTableView. If those changes make
it so that my code SHOULD work, I have no Idea why it isn't
working... If you would like a copy of my project just send me a
direct e-mail and I will send it.

Hi, Jeremy,
You appear to have a few corrections that need to be made with
your code. To resolve these will help you on your way. You
should make the following changes before you try to get things
working:
1. Remove the extraneous retain from your categoriesArray
instantiation -- -alloc and -init produce a retained object.
2. Change:
NSString *string;
string = [NSString init];
string = @"Main Category";
to
NSString *string = @"Main Category";
or
NSString *string = [NSString stringWithString:@"Main Category"];
3. Also note that [NSString init] is improper; you need [[NSString
alloc] init] or [NSString string] -- but no matter what, it's a
waste if you immediately set string to @"Main Category".
4. Is your controller class with the code that you gave all set up
as the dataSource for the table view? You'll need to connect that
in Interface Builder.
If I can be of any more service, let me know.
Cheers,
Andrew

This is how I am attempting to do it...
In awakeFromNib:
categoriesArray = [[[NSMutableArray alloc] init] retain];
NSString *string;
string = [NSString init];
string = @"Main Category";
[categoriesArray addObject:string];
[categories selectRow:1 byExtendingSelection:NO];
[categories scrollRowToVisible:1];
And my informal protocols:
- (int)numberOfRowsInTableView:(NSTableView *)aTableView
{
return [categoriesArray count];
}
- (id)tableView:(NSTableView *)aTableView objectValueForColumn:
(NSTableColumn *)aTableColumn row:(int)row
{
return [categoriesArray objectAtIndex:row];
}
The NSTableView is not being populated at all... No rows, and
nothing else....

I am trying to figure NSTableViews out. I have two table views
inside
of my window. The code I have is completely useless and not
working.
Can anyone explain how to populate an NSTableView using arrays?
If you
could that would be greatly appreciated.
You should explain how what you are trying to do differs from
what is
covered in the various basic tutorials for using NSTableViews;
otherwise we will not know how to address your question.
