title: Google sheets unique multiple columns and output multiple columns
body: <p>I need some help working through this problem. I have multiple columns of data and I want to make it so that I only keep unique values and return the items to their respective columns.</p>
  
  <pre><code>1 2 3 6
  1 1 4 7  
  2 3 5 8
  </code></pre>
  
  <p>would end up like this:</p>
  
  <pre><code>1 3 4 6
  2   5 7
        8
  </code></pre>
  
  <p>Right now I can do with one column using the <code>=unique()</code> function but I want to be able to put a new column of data and it would only spit out the unique items from that into the new table.</p>
