body: <p>Currently I have this view but I would like to change it such that the most recent employee 'Stritt' gets all the sales cause he made the last one.</p>

  <p>It should look like this:</p>
  <pre><code>   cal_date     id  sales   emp
      2021-01-04  24  0.85    Stritt
      2021-01-29  24  11.4    Stritt
      2021-01-31  24  -5.7    Stritt
      2021-02-01  24  0.85    Stritt
      2021-02-26  24  1.00    Stritt
      2021-01-30  33  5.33    Dom
      2021-03-10  33  3.45    Dom
