Use Pagination With sortBy in Laravel?

I'm trying to pull a few rows with a model in Laravel using pagination and sortBy.

Here is my Controller (without sorting):

    public function all(){
       $results['rows'] = Items::where('XXXX','YYYY')->paginate(32);
       return view('page', $results);
    }

This works fine. When I add sorting to it:

public function all(){
       $results['rows'] = Items::where('XXXX','YYYY')->paginate(32)->sortBy('TTT');
       return view('page', $results);
    }

The pagination on the blade template crashes. This is my code in blade:

<?php echo $rows->render(); ?>

I read a few questions here with a similar question, though the code didn't seem to be like mine and couldn't figure out how to implement it on my code. Any help would be much appreciated.

As Viney said, use orderBy() instead of sortBy():

$results['rows'] = Items::where('XXXX','YYYY')->orderBy('TTT')->paginate(32);
