因此，我能够创建一个粘性标头表，并且工作正常。问题在于，我需要用多行标题制作另一个表，并且到目前为止，我使用的方法不起作用，如下面的代码所示。
.table-wrapper {
position: relative;
overflow-y: auto;
height: 200px;
width: 200px;
}
table {
border: 1px solid #DDD;
vertical-align: middle;
text-align: center;
border-collapse: collapse;
border-spacing: 0
}
table tr th,
table tr td{
border: 1px solid #DDD;
background-color: #FFF;
padding: 4px;
}
table thead tr th {
position: sticky;
top: 0;
}<div class="table-wrapper">
<table>
<thead>
<tr>
<th rowspan="2">
Header
</th>
<th colspan="2">Colspan column</th>
</tr>
<tr>
<th>
A
</th>
<th>
B
</th>
</tr>
</thead>
<tbody>
<tr>
<td>Line 1</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 2</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 3</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 4</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 5</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 6</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 7</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 8</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 9</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Line 10</td>
<td>a</td>
<td>b</td>
</tr>
</tbody>
</table>
</div>
是否可以仅使用CSS达到我想要的？

您快到了，您可以简单地将表格嵌入<th>中，并以此方式添加其他行。
.table-wrapper {
position: relative;
overflow-y: auto;
height: 200px;
width: 200px;
}
table {
border: 1px solid #DDD;
vertical-align: middle;
text-align: center;
border-collapse: collapse;
border-spacing: 0
}
table tr th,
table tr td{
border: 1px solid #DDD;
background-color: #FFF;
padding: 4px;
}
table thead tr th {
position: sticky;
top: 0;
}<div class="table-wrapper">
<table>
<thead>
<tr>
<th rowspan="2" colspan="1">
Header
</th>
<th rowspan="2" colspan="2">

<tr>
<td colspan="2">Colspan column</td>
</tr>
<tr>
<td colspan="1">A</td>
<td colspan="1">B</td>
</tr>
</table>
</th>

使用现代浏览器，您可以简单地添加position：sticky（某些IOS设备为-webkit-sticky）。请注意，您需要相对于直接容器添加位置：相对于THEAD，TFoot或TBODY。另外，您需要使用z-index设置索引顺序，以便内容在粘滞dom元素下滚动。因此，如果标题具有粘性，并且第一列也具有粘性（是的，这也是可行的），则需要为其设置z-index级别。
如果您使用在页眉或页脚单元格上带有边框的表，则将无法正常工作，页眉或页脚的边框会随内容滚动，而在滚动内容时会消失。您可以在标题单元格上使用box-shadow来模拟边框。
thead,
tbody,
tfoot {
/* cell container need relative position */
position: relative;
}
/* sticky header */
thead th {
/* ios devices */
position: -webkit-sticky;
position: sticky;
left: 0;
top: 0;
/* index order is needed for the different sticky levels */
z-index: 1;
}
/* sticky first column */
thead th:first-of-type {
top: 0;
left: 0;
z-index: 3;
}
tbody td:first-of-type {
position: -webkit-sticky;
position: sticky;
left: 0;
z-index: 1;
/* sitcky TD/TH need background color */
background-color: white;
/* adding right borde / border gets hidden when scrol so use box-shadow: */
box-shadow: 2px 0 0 -1px gray;
}
/* sticky footer */
tfoot th {
position: sticky;
bottom: 0;
}
tfoot th:first-of-type {
left: 0;
z-index: 3;
}
/* default styling */
@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap');
