title: Compare multiple data from rows
body: <p>I'm looking for a way to compare multiple rows with data to each other, trying to find the best possible match. Each number in every column must be an approximately match the other numbers in the same column.</p>
  
  <p>Example:</p>
  
  <ul>
  <li>Customer #1: <strong>1  5  10  9  7  7  8   2  3</strong></li>
  <li>Customer #2: 10 5  9   3  5  7  4   3  2</li>
  <li>Customer #3: <strong>1  4  10  9  8  7  6   2  2</strong></li>
  <li>Customer #4: 9  5  6   7  2  1  10  5  6</li>
  </ul>
  
  <p>In this example customer #1 and #3 is quite similar, and I need to find a way to highlight or sort the rows so I can easily find the best match.</p>
  
  <p>I've tried using conditional formatting to highlight the numbers that are the similar, but that is quite confusing, because the amount of data is quite big.</p>
  
  <p>Any ideas of how I could solve this?</p>
  
  <p>Thanks!</p>
