vertical-align:middle a div inside a floating div?

Question

为什么第三列中的黑色条纹没有在父级中间垂直对齐div？而是在顶部下方对齐一点。有办法解决吗？

HTML:

<table border="1">
  <tbody>
    <tr>
      <td>ADMIN<br>:(</td>
      <td>222387</td>
      <td width='50' style='position:relative'>
        <div class='data'>59853.94</div>
        <div class="bar-chart-bar">
          <div class="bar" style='width:50%; background-color:#B8E4F5'>
          <div style="height:10px; background-color:black; width:100%;vertical-align:middle; display: inline-block"></div>            
          </div>
        </div>
      </td>
      <td width="50">0</td>
      <td>59853.94</td>
      <td>4189.82</td>
      <td>7</td>
    </tr>
  </tbody>
</table>

CSS:

.bar-chart-bar {
  background-color: #e8e8e8;
  display: block;
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: -1;
}

.bar {
  float: left;
  height: 100%;
}

.data {

}

.table > tbody > tr > td {
  vertical-align: middle;
}

table {
  font-size: 12px;
}

Answer 1

在这种情况下，vertical-align for inline-block 元素与其他元素相关而不是与容器本身相关，您可以添加这样的参考元素：

.bar:before {
  content:"";
  display:inline-block;
  height:100%;
  margin-right:-4px;
  vertical-align:middle;
}

Answer 2

您的 .bar class，您可以添加

display:flex;
flex-direction:column;
justify-content:center;

以及删除

vertical-align: middle;
display: inline-block;

来自你的 .data class。 Here is the result. The reason this wasn't working for you is that vertical-align doesn't really behave the way you want it to unless your element is in a table cell. See this 了解有关垂直对齐的更多信息。
