html - Div 的宽度被忽略

Question

我已经尝试重新使用一些在网页上显示自定义警报的方法。由于某种原因，代码在旧页面上可以正常工作，但在我的新页面上却不能。

              Text
              <br>
              <table width="100%">
                <tbody>
                  <tr>
                    <td width="100%" align="right"><span onclick="remindPassword(document.getElementById('txtForgotPasswordName').value)" class="button">Button</span>
                    </td>
                  </tr>
                </tbody>
              </table>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

问题是:

尽管 div 的 width 设置为 800px，但它被忽略了。

有什么想法吗？
