显示页脚总是在底部

Question

我有 html 用于呈现 PDF 文件，我需要将<tfoot>部分始终显示在每个页面的底部，即使页面内容很小。

<div class="pdf-position-top pdf-content-center">
  <table>
    <thead>
      <tr>
        <th>
          <div class="print-banner">
            <span class="banner-text-repeat">Some Text</span>
          </div>
        </th>
      </tr>
    </thead>
    @RenderSection("TableBody", required: true)
    <tr>
      <td>
        <div class="pdf-content-center">@RenderBody()</div>
      </td>
    </tr>
    <tfoot>
      <tr>
        <td>
        <!--START print-banner top-->
          <div class="print-banner">
            <span class="banner-text-repeat">Some Text</span>
          </div>
        </td>
      </tr>
    </tfoot>
  </table>
</div>

Answer 1

From documentation of header/footer

var myObserver = {
  next: (val) => {},
  error: (err) => {},
  complete: () => {}
};

var mySubscription: Subscription = myObservable.subscribe(myObserver);

// then, if later you want to unsubscribe:

mySubscription.unsubscribe()
