Adding NSTableView to NSView Programmatically - cocoa

Question

I am having a bit of trouble adding a NSTableView to an NSView programatically. The view is the first view of an NSSplitView. My Pointers are set up right i am sure of it because I can add a NSButton to the view no problem. Also my tableview's delegate and datasource methods are working as expected. If I use interface builder to add the table view to my view it works. However, I dont want to use IB. I would like to be able to do this through code. Here is the code I am currently using.
-(void)awakeFromNib{
tableData = [[NSMutableArray alloc]initWithObjects:#"March",#"April",#"May", nil];
tableView = [[NSTableView alloc]initWithFrame:firstView.frame];
[tableView setDataSource:self];
[tableView setDelegate:self];
[firstView addSubview:tableView];
NSButton *j = [[NSButton alloc]initWithFrame:firstView.frame];
[j setTitle:#"help"];
[firstView addSubview:j];
}
The NSButton object appears on screen although if I comment out the button the tableview does not appear. What am I doing wrong. Thanks for the help.

Thank you, from your help I was able to figure this out. IB automatically inserts the NSScrollview around the table view and it also inserts a column for you. In order to do it this from code you need to allocate a scroll view and a column. Here is what I am currently utilizing if anyone else comes across this problem.
-(void)awakeFromNib{
tableData = [[NSMutableArray alloc]initWithObjects:#"March",#"April",#"May", nil];
NSScrollView * tableContainer = [[NSScrollView alloc] initWithFrame:firstView.bounds];
//This allows the view to be resized by the view holding it
[tableContainer setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];
tableView = [[NSTableView alloc] initWithFrame:tableContainer.frame];
[tableView setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];
NSTableColumn *column =[[NSTableColumn alloc]initWithIdentifier:#"1"];
[column.headerCell setTitle:#"Header Title"];
[tableView addTableColumn:column];
[tableView setDataSource:self];
[tableView setDelegate:self];
[tableContainer setDocumentView:tableView];
[firstView addSubview:tableContainer];
//You mentioned that ARC is turned off so You need to release these:
[tableView release];
[tableContainer release];
[column release];
}
Thanks for your help.

NSTableView by default is in NSScrollView. So You can do it like this:
tableData = [[NSMutableArray alloc] initWithObjects:#"March",#"April",#"May", nil];
NSScrollView * tableContainer = [[NSScrollView alloc] initWithFrame:firstView.frame];
tableView = [[NSTableView alloc] initWithFrame:firstView.frame];
[tableView setDataSource:self];
[tableView setDelegate:self];
[tableContainer setDocumentView:tableView];
[firstView addSubview:tableContainer];
//You mentioned that ARC is turned off so You need to release these:
[tableView release];
[tableContainer release];
