title: Total Sum/Level of Detail in Google Data Studio
body: <p>In Google Data Studio I have a small table including a dimension and a metric</p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>Channel</th>
  <th>User</th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>A</td>
  <td>1.000</td>
  </tr>
  <tr>
  <td>B</td>
  <td>2.500</td>
  </tr>
  <tr>
  <td>C</td>
  <td>500</td>
  </tr>
  </tbody>
  </table>
  </div>
  <p>Is there a way to calculate the total sum across the dimension (like an LOD) which is shown as an additional column next to the user?
  The solution should look like this</p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>Channel</th>
  <th>User</th>
  <th>Total Users</th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>A</td>
  <td>1.000</td>
  <td>4.000</td>
  </tr>
  <tr>
  <td>B</td>
  <td>2.500</td>
  <td>4.000</td>
  </tr>
  <tr>
  <td>C</td>
  <td>500</td>
  <td>4.000</td>
  </tr>
  </tbody>
  </table>
  </div>
