Scrollable table body using bootstrap4

Question

Using Bootstrap-4 I am not able to apply scroll for table body with fixed header. I am using min-height as well as overflow for applying scroll to table body. Does bootstrap4 doesn't support scroll on table body? Below snippet explains the problem more clearly.

Am I going wrong somewhere?

.tbody {
  min-height:10px;
  overflow-y:scroll;
}

        <td>Doe</td>

      </tr>
      <tr>
        <td>Mary</td>
        <td>Moe</td>
        <td>[email protected]</td>
      </tr>
      <tr>
        <td>July</td>
        <td>Dooley</td>
        <td>[email protected]</td>
      </tr>
    </tbody>
  </table>
</div>

After setting display:block property to table you can set height and widths.

Try this:

table {
  display:block;
  height : <set your desired height>;
  overflow-y : scroll;
}
