title: placeholder for empty uitableview section
body: <p>After lots of searching, I can't seem to find what I'm looking for.</p>
  
  <p>I have a UITableview where some of the sections may be blank to begin with. Here's a picture to help get an idea of what I'm talking about. I want to have some <strong>TEXT</strong> (not a table cell) in the middle between the footer and the header. Is there anything that I may have overlooked?</p>
