html - 如何使 's height of position:fixed column follow its content' s 高度？

Question

目前，我的页面中有一个表格，我正在尝试卡住第一列。使用 position: fixed 卡住列工作正常对于那个特定的列。

但是还有一个问题。当内容超过一行时，<tr>不会根据其内容扩展其高度。那么，有什么解决办法吗？

这是我的演示: https://jsfiddle.net/yusrilmaulidanraji/ckfdubsf/121/

#table-wrapper {
  width: 95%;
  float: left;
  overflow-x: scroll;
  background: #ddd;
}

table {
  background: #fff;
  width: 1200px;
  text-align: center;
  overflow: hidden;
  position: relative;
}

table thead tr th {
  width: 15em;
}

table thead tr th:first-child,
table tbody tr td:first-child {
  top: auto;
  left: 0.5;
  position: fixed;
  width: 6em;
}

table thead tr th:nth-child(2),
table tbody tr td:nth-child(2) {
  padding-left: 7em;
  /*to show second column behind the first*/
}

<button id="left">&larr;</button>
<button id="right">&rarr;</button>

<div id="table-wrapper">
  <table border="1">
    <thead>
      <tr>
        <th>Heading1</th>
        <th>Heading2</th>
        <th>Heading3</th>
        <th>Heading4</th>
        <th>Heading5</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>1<br/>asdasdada</td>
        <td>12</td>
        <td>13</td>
        <td>14</td>
        <td>15</td>
      </tr>
      <tr>
        <td>2<br/>asdasdada<br/>asdasdada</td>
        <td>22</td>
        <td>23</td>
        <td>24</td>
        <td>25</td>
      </tr>
      <tr>
        <td>3<br/>asdasdada</td>
        <td>32</td>
        <td>33</td>
        <td>34</td>
        <td>35</td>
      </tr>
      <tr>
        <td>4<br/>asdasdada<br/>asdasdada<br/>asdasdada<br/>asdasdada<br/>asdasdada</td>
        <td>42</td>
        <td>43</td>
        <td>44</td>
        <td>45</td>
      </tr>
      <tr>
        <td>5<br/>asdasdada</td>
        <td>52</td>
        <td>53</td>
        <td>54</td>
        <td>55</td>
      </tr>
    </tbody>
  </table>

</div>

您可以遍历所有 td 固定元素，然后将这些高度设置为默认 td 元素。

  $('table tbody tr td:first-child').each(function(){
      var height = $(this).height();
      $(this).parent().find('td').height(height);
  });
