Adding horizontal scrolling shadows effect

Question

I want to add an inset shadow to indicate that there is more content to scroll. The best way I can explain it is with a drawing:

I'm using Bootstrap as a framework and this is exactly what I'm working on:

Below is the code:

<div class="table-responsive">
  <table class="table">
    <thead>
      <tr>
        <th scope="col">#</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
        <th scope="col">Heading</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <th scope="row">1</th>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
      </tr>
      <tr>
        <th scope="row">2</th>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
      </tr>
      <tr>
        <th scope="row">3</th>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
        <td>Cell</td>
      </tr>
    </tbody>
  </table>
</div>

You can do Horizontal scrolling shadows effect with following background css.

.table-responsive{
  background-image: linear-gradient(to right, white, white), linear-gradient(to right, white, white), linear-gradient(to right, rgba(0, 0, 20, .50), rgba(255, 255, 255, 0)), linear-gradient(to left, rgba(0, 0, 20, .50), rgba(255, 255, 255, 0));
  /* Shadows */
  /* Shadow covers */
  background-position: left center, right center, left center, right center;
  background-repeat: no-repeat;
  background-color: white;
  background-size: 20px 100%, 20px 100%, 10px 100%, 10px 100%;
  background-attachment: local, local, scroll, scroll;
  }
