我想制作粘性表头（总是在顶部），但我有两个问题：
这是一个例子（仅从其他问题分叉）：
HTML：
<section class="">
<div class="container">
<table>
<thead>
<tr class="header">
<th>
Table attribute name
<div>Table attribute name</div>
</th>
<th>
Value
<div>Value</div>
</th>
<th>
Description
<div>Description</div>
</th>
</tr>
</thead>
<tbody>
<tr>
<td>align</td>
<td>left, center, right</td>
<td>Not supported in HTML5. Deprecated in HTML 4.01. Specifies the alignment of a table according to surrounding text</td>
</tr>
<tr>
<td>bgcolor</td>
<td>rgb(x,x,x), #xxxxxx, colorname</td>
<td>Not supported in HTML5. Deprecated in HTML 4.01. Specifies the background color for a table</td>
</tr>
<tr>
<td>border</td>
<td>1,""</td>
<td>Specifies whether the table cells should have borders or not</td>
</tr>
<tr>
<td>cellpadding</td>
<td>pixels</td>
<td>Not supported in HTML5. Specifies the space between the cell wall and the cell content</td>
</tr>
<tr>
<td>cellspacing</td>
<td>pixels</td>
<td>Not supported in HTML5. Specifies the space between cells</td>
</tr>
<tr>
<td>frame</td>
<td>void, above, below, hsides, lhs, rhs, vsides, box, border</td>
<td>Not supported in HTML5. Specifies which parts of the outside borders that should be visible</td>
</tr>
<tr>
<td>rules</td>
<td>none, groups, rows, cols, all</td>
<td>Not supported in HTML5. Specifies which parts of the inside borders that should be visible</td>
</tr>
<tr>
<td>summary</td>
<td>text</td>
<td>Not supported in HTML5. Specifies a summary of the content of a table</td>
</tr>
<tr>
<td>width</td>
<td>pixels, %</td>
<td>Not supported in HTML5. Specifies the width of a table</td>
</tr>
</tbody>
</table>
</div>
</section>
CSS：
html, body{
margin:0;
padding:0;
height:100%;
}
section {
position: relative;
border: 1px solid #000;
padding-top: 37px;
background: #500;
width: 200px;
height: 200px;
}
table {
border-spacing: 0;
width:100%;
}
td + td {
border-left:1px solid #eee;
}
td, th {
border-bottom:1px solid #eee;
background: #ddd;
color: #000;
width: 100px;
}
th {
height: 0;
line-height: 0;
padding-top: 0;
padding-bottom: 0;
color: transparent;
border: none;
white-space: nowrap;
}
th div{
position: absolute;
background: transparent;
color: #fff;
top: 0;
line-height: normal;
border-left: 1px solid #800;
}
th:first-child div{
border: none;
}
我想只使用没有js技巧的css解决方案。可以明确定义列的宽度，但不能高度。
你可以修复我的例子并解释它应该如何运作吗？
编辑： 我已经检查了问题： Fixed header table with horizontal scrollbar and vertical scrollbar on - 这对我来说不是解决方案，因为前两个答案使用JQuery，而@Anshuman建议的第三个答案也是基于js的（js只是隐藏在html标签中的onscroll =）
大多数解决方案都使用两个表而不是thead，我想避免这种情况 - 我希望使用thead部分设置已经渲染的html表。
答案 0 :(得分：1)
使用您的html结构，您可以在容器和tbody上调度滚动条。但只有当容器一直向右滚动时才会看到tbody滚动条。
不太确定这是你想要的（用于演示的宽度和高度，如果这是你想要做的那样根据你的需要更新它们）：
table {
display: block;
width: 75vw;
}
section {
width: 25vw;
overflow: hidden;
position: relative;
overflow-x: auto;
}
thead,
tbody {
display: block;
}
tbody {
height: 150px;
overflow-x: hidden;
overflow-y: auto;
}
tr {
display: table;
border-collapse: collapse;
width: 75vw;
table-layout: fixed;
}
th,
td,
th div {
box-shadow: 0 0 0 1px;
}
th div {
position: absolute;
top: 0;
left: auto;
width: 25vw;
background: gray;
}<section>
<table>
<thead>
<tr class="header">
<th>
Table attribute name
<div>Table attribute name</div>

<div>Value</div>
