title: Finding the row with the biggest difference of two columns in excel
body: <p>I have a table with three columns. One for the date, the other min temperature and the other max temperature. I want to find the day that showed the greatest difference between the two temperatures. How do I do that in excel?
  This is for instance what i have</p>
  <pre><code>02/02/2010  30.0   31.0
  02/03/2010  29.4   27.2
  </code></pre>
  <p>so for instance 02/03/2010 had the greatest variation in temperature</p>
