title: Printing string with two columns
body: <p>I'm trying to print a string with two fixed columns.  For example, I'd like to be able to print:</p>
  
  <pre><code>abc       xyz
  abcde     xyz
  a         xyz
  </code></pre>
  
  <p>What is the correct way to format the output string when printing to achieve this?  Also, how is this done before version 2.6 and after version 2.6?</p>
