title: How do I set the background color of a grouped UITableView?
body: <p>I want conjoined email &amp; password textfields like so - </p>

  <p>See how both the fields are nicely rounded &amp; the background color is blue.</p>
  
  <p>The way I have implemented this is to create a custom tableViewCell with a label and a text field in a grouped table view probably with a single section and two rows one of which is for username and other for password.</p>
  
  <p>What I have got is below. I have come close to implementing this but I am getting a weird grey background. How do I get rid of this grey background?</p>
