title: UITableView:viewForHeaderInSection - Header Text?
body: <p>In my App (iPad) there was a need to create a UITableView that contained a number of columns.
  To do this I had to create a custom UITableViewCell to provide the columns needed.</p>
  
  <p>Now, it's time to place headers on these columns.  In the 'viewForHeaderInSection' delegate I want to placed a label that spreads the width of the table.</p>
  
  <p>All has gone well, the Background colour has been set and that reaches out to the width of the view nicely.</p>
  
  <p>But when I go to use:</p>
  
  <pre><code>label.text = [NSString stringWithFormat:@"  Date      Dist       Litres        Cost($)"];
  </code></pre>
  
  <p>I don't get the text spreading out to represent the above example.  What I get is more like:</p>
  
  <pre><code>" Date Dist Litres Cost($)"
  </code></pre>
  
  <p>How do I restore the spaces I need in the Header Text?</p>
