How to make NSTableView transparent?

Question

I want to make transparent NSTableView.
I am using WindowController class here.
I was trying this:

- (void)windowDidLoad
{
     [super windowDidLoad];
     [[self enclosingScrollView] setDrawsBackground: NO];
     [[self enclosingScrollView] setBorderType:NSNoBorder];

}

- (BOOL)isOpaque {

      return NO;
} 
- (void)drawRect:(NSRect)drawRect
{
     [super drawRect: drawRect];
}

But when i was writing this code i can't found enclosingScrollView in help window.
you can see here..

Any help?? Please remember me or correct me if i am doing something wrong.
Thank you.

If you have an NSScrollView enclosing your NSTableView, you can set the scroll view's drawsBackground property to NO like this:

yourScrollView.drawsBackground = NO;

If your app needs to display a transparent table view, set the background color of the table view to be clear and set the enclosing scroll view to not draw its background. The following code snippet shows one way to display a transparent table:

Swift:

yourTableView.backgroundColor = NSColor.clear
yourTableView.enclosingScrollView?.drawsBackground = false

Objective-C

[theTableView setBackgroundColor:[NSColor clearColor];
[[theTableView enclosingScrollView] setDrawsBackground:NO];
