title: Adding days to sysdate based off of values in a column
body: <p>I am trying to create a manual table based off of a currently built views table. 
  The structure of this current table is as follows:</p>
  
  <pre>
  ID | Column1 | Column2 | Buffer Days
  
  1  | Asdf    | Asdf1   | 91
  2  | Qwert   | Qwert1  | 11
  3  | Zxcv    | Zxcv1   | 28
  </pre>
  
  <p>The goal is to add a 4th column after Buffer Days that lists the sys date + the number in buffer days</p>
  
  <p>So the outcome would look like:</p>
  
  <pre>
  ID | Column1 | Column2 | Buffer Days | Lookout Date
  
  1  | Asdf    | Asdf1   | 91          | 02-Jan-18
  </pre>
