title: Sum into aggregate rows based on duplicate column value
body: <p>I have a large data set that looks something like this:</p>
  
  <pre><code>239617920   0   1   1   1
  239617917   0   1   1   1
  239617911   1   1   0   1
  239617911   1   0   0   1
  239617890   0   0   0   1
  239617885   1   1   0   1
  </code></pre>
  
  <p>For each row, I want to be able to sum up the values of columns B, C, D, and E if column A values are equal, into one aggregate row.
  Therefore, I want my output to be </p>
  
  <pre><code>239617920   0   1   1   1
  239617917   0   1   1   1
  239617911   2   1   0   2
  239617890   0   0   0   1
  239617885   1   1   0   1
  </code></pre>
  
  <p>Since I have <code>239617911</code> listed twice.</p>
  
  <p>Is there a way to do this in excel?</p>
