title: UITableView HeaderView margin when removing separator's left space
body: <p>I've removed the separator left margin from my tableview using in the <strong>viewDidLoad</strong>:</p>
  
  <pre><code>self.tableView.layoutMargins = UIEdgeInsetsZero
  self.tableView.separatorInset = UIEdgeInsetsZero
  </code></pre>
  
  <p>In my <strong>cellForRowAtIndexPath</strong>:</p>
  
  <pre><code>cell.layoutMargins = UIEdgeInsetsZero
  </code></pre>
  
  <p>The problem is that the header and footer views has been moved too and I want to keep it aligned with the cells' content.</p>

  <p>I've tried to change the frame in the <strong>willDisplayHeaderView</strong> and <strong>willDisplayFooterView</strong> without success. Any suggestion? Thanks!</p>
