title: Highlighting cell if one date is after another?
body: <p>I have a couple columns of data, and I am trying to highlight those instances where the second date occurs before the first, to show if there are any mistakes in the data.</p>
  
  <pre><code>ID  Start Date  End Date
  1    01/01/15    01/15/15
  2    01/06/15    01/02/15
  3    01/06/15    01/03/15
  4    01/11/15    01/13/15
  </code></pre>
  
  <p>I would like to be able to highlight the cells where the end date is earlier than the start date. All of the date conditional formatting links I have been directed to are for basing it off of current date, or one specific date, and I am kind of lost. </p>
  
  <p>Thanks!</p>
