title: Python PrettyTable: Add title above the table's header
body: <p>I have a script which generates multiple tables, which all have the same column names and very similar data. Until now I've been making each table unique by printing a title before it, i.e.:</p>
  
  <pre><code>print("Results for Method Foo")
  #table 1
  print("Results for Method Bar")
  #table 2 
  </code></pre>
  
  <p>and so on. But that's not really pretty..</p>
  
  <p>Although it seems like an obvious use case, I couldn't find anywhere the option to do something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/w5ljE.png" rel="noreferrer"><img src="https://i.stack.imgur.com/w5ljE.png" alt="PrettyTable with title"></a></p>
  
  <p>Any ideas about how I could achieve this?</p>
  
  <p><strong>Just in case it matters:</strong> I'm using python 3.4 with, with a virtualenv  and prettytable version 0.7.2 </p>
