position：absolute和vertical-align：middle

Question

如何在我的示例中设置第三列以使vertical-align: middle作为所有其他行？我意识到问题出在position: absolute，但我无法弄清楚如何解决问题。

即使使用top定位也不适用于.data。

我的HTML：

<table border="1">
  <tbody>
    <tr>
      <td>ADMIN</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>
        </div>
      </td>
      <td width="50">0</td>
      <td>59853.94</td>
      <td>4189.82</td>
      <td>7</td>
    </tr>
  </tbody>
</table>

我的CSS：

.bar-chart-bar {
  background-color: #e8e8e8;
  display: block;
  position: relative;
  width: 100%;
  height: 20px;
}

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

.data {
  position: absolute;
  z-index: 1;
  display: block;
  top: 10;
}

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

table {
  font-size: 12px;
}

Answer 1

是的，您需要从.data中移除position: absolute，并绝对定位.bar-chart-bar并相应地设置z-index：

.bar-chart-bar {
  background-color: #e8e8e8;
  display: block;
  position: absolute;
  width: 100%;
  height: 20px;
  top: 0;
  left: 0;
  z-index: -1;
}

将display:table添加到班级data

＆＃13;

＆＃13;

.bar-chart-bar {
  background-color: #e8e8e8;
  display: block;
  position: relative;
  width: 100%;
  height: 20px;
}

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

.data {
  position: absolute;
  z-index: 1;
  display:table;
}

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

table {
  font-size: 12px;
}

＆＃13;

<table border="1">
  <tbody>
    <tr>
      <td>ADMIN</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>
        </div>
      </td>
      <td width="50">0</td>
      <td>59853.94</td>
      <td>4189.82</td>
      <td>7</td>
    </tr>
  </tbody>
</table>

＆＃13;

删除位置并使数据div成为bar div的子项。

.bar-chart-bar {
  background-color: #e8e8e8;
  display: block;
  width: 100%;
}

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

.data {
  z-index: 1;
}

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

table {
  font-size: 12px;
}

<table border="1">
  <tbody>
    <tr>
      <td>ADMIN</td>
      <td>222387</td>
      <td width='50' style='position:relative'>
        <div class="bar-chart-bar">
            <div class="bar" style='width:50%; background-color:#B8E4F5'>
                <div class='data'>59853.94</div>
            </div>
        </div>
      </td>
      <td width="50">0</td>
      <td>59853.94</td>
      <td>4189.82</td>
      <td>7</td>
    </tr>
  </tbody>
</table>
