对于纯CSS方法，你需要一个带有overflow-y: auto;并决定如何隐藏滚动/溢出行:

覆盖一个不透明的粘头(位置:粘;上图:0;z-index: 1;)，就像@RokoCBuljan的答案一样。 切换行可见性(通过如下所示在属性后设置tr:)。

注意容器可以是一个外部<div>，或者<table>本身，或者它的一部分(例如<tbody>)。后面两个你需要设置display: block;所以实际上他们被当成了潜水者。

请看下面一个修改后的@giulio的解决方案:

:root { --height-height: 150px; /* cell width has to reserve some space for scrolling. Hence the sum < 100% */ --cell-width: 85px; } .header-fixed { width: 200px; } /* Treat all as divs */ .header-fixed > thead, .header-fixed > tbody, .header-fixed > thead > tr, .header-fixed > tbody > tr, .header-fixed > thead > tr > th, .header-fixed > tbody > tr > td { display: block; } /* Prevent header to wrap */ .header-fixed > thead > tr > th { white-space: nowrap; background-color: lightgrey; } .header-fixed > tbody > tr:after, .header-fixed > thead > tr:after { content: ' '; display: block; visibility: hidden; clear: both; } .header-fixed > tbody { overflow-y: auto; height: var(--height-height); } .header-fixed > tbody > tr > td, .header-fixed > thead > tr > th { width: var(--cell-width); border: thin solid grey; float: left; } <table class="header-fixed"> <thead> <tr> <th>Header 1</th> <th>Header 2</th> </tr> </thead> <tbody> <tr> <td>cell 11</td> <td>cell 12</td> </tr> <tr> <td>cell 21</td> <td>cell 22</td> </tr> <tr> <td>cell 31</td> <td>cell 32</td> </tr> <tr> <td>cell 41</td> <td>cell 42</td> </tr> <tr> <td>cell 51</td> <td>cell 52</td> </tr> <tr> <td>cell 61</td> <td>cell 62</td> </tr> <tr> <td>cell 71</td> <td>cell 72</td> </tr> <tr> <td>cell 81</td> <td>cell 82</td> </tr> <tr> <td>cell 91</td> <td>cell 92</td> </tr> </tbody> </table>

注意:如果你有>2列，你需要相应地摆弄var(——cell-width)变量。

到目前为止，我所见过的最好的解决方案是CSS，具有良好的跨浏览器支持，并且没有对齐问题，这是来自codingrabbithole的解决方案

table {
  width: 100%;
}
thead, tbody tr {
  display: table;
  width: 100%;
  table-layout: fixed;
}
tbody {
  display: block;
  overflow-y: auto;
  table-layout: fixed;
  max-height: 200px;
}

清洁解决方案(仅适用于CSS)

.table-fixed tbody {
    display:block;
    height:85vh;
    overflow:auto;
}
.table-fixed thead, .table-fixed tbody tr {
    display:table;
    width:100%;
}


<table class="table table-striped table-fixed">
    <thead>
        <tr align="center">
            <th>Col 1</th>
            <th>Col 2</th>
            <th>Col 3</th>
            <th>Col 4</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Content 1</td>
            <td>Content 1</td>
            <td>Content 1</td>
            <td>Content 1</td>
        </tr>
        <tr>
            <td>Longer Content 1</td>
            <td>Longer Content 1</td>
            <td>Longer Content 1</td>
            <td>Longer Content 1</td>
        </tr>
    </tbody
</table

<style>

thead, tbody
{
    display: block;
}

tbody 
{
   overflow: auto;
   height: 100px;
}

th,td
{
    width: 120px;
}

</style>

<table class="table table-bordered table-striped">
    <thead style="background-color:lightgreen">
        <tr>
            <th>Id</th><th>Name</th><th>Roll</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
    </tbody>
</table>

根据@Roko C. Buljan的回答，如果你尝试添加行跨度，当你滚动时，只有第一个th会被固定。

.tableFixHead { overflow: auto; height: 100px; } .tableFixHead thead th { position: sticky; top: 0; z-index: 1; } /* Just common table stuff. Really. */ table { border-collapse: collapse; width: 100%; } th, td { padding: 8px 16px; } th { background:#eee; } <div class="tableFixHead"> <table> <thead> <tr> <th rowspan="3">TH 1</th> <th>TH 2.1</th> <th>TH 3.1</th> </tr> <tr > <th>TH 2.2</th> <th>TH 3.2</th> </tr> <tr > <th>TH 2.3</th> <th>TH 3.3</th> </tr> </thead> <tbody> <tr><td>A1</td><td>A2</td><td>A3</td></tr> <tr><td>B1</td><td>B2</td><td>B3</td></tr> <tr><td>C1</td><td>C2</td><td>C3</td></tr> <tr><td>D1</td><td>D2</td><td>D3</td></tr> <tr><td>E1</td><td>E2</td><td>E3</td></tr> </tbody> </table> </div>

如果你想固定行跨度，你可以添加这行

.tableFixHead thead tr:nth-child(2) th {
    top: 34px; /* change the number according to your need  */
}

.tableFixHead thead tr:nth-child(3) th {
    top: 68px; /* change the number according to your need  */
}

作为示例，您可以检查这个片段

.tableFixHead { overflow: auto; height: 200px; } .tableFixHead thead th { position: sticky; top: 0; z-index: 1; } .tableFixHead thead tr:nth-child(2) th { top: 34px; /* change the number according to your need */ } .tableFixHead thead tr:nth-child(3) th { top: 68px; /* change the number according to your need */ } /* Just common table stuff. Really. */ table { border-collapse: collapse; width: 100%; } th, td { padding: 8px 16px; } th { background:#eee; } <div class="tableFixHead"> <table> <thead> <tr> <th rowspan="3">TH 1</th> <th>TH 2.1</th> <th>TH 3.1</th> </tr> <tr > <th>TH 2.2</th> <th>TH 3.2</th> </tr> <tr > <th>TH 2.3</th> <th>TH 3.3</th> </tr> </thead> <tbody> <tr><td>A1</td><td>A2</td><td>A3</td></tr> <tr><td>B1</td><td>B2</td><td>B3</td></tr> <tr><td>C1</td><td>C2</td><td>C3</td></tr> <tr><td>D1</td><td>D2</td><td>D3</td></tr> <tr><td>E1</td><td>E2</td><td>E3</td></tr> </tbody> </table> </div>

如果你用n -child(number)手动指定number，上面的代码段将正常工作

把表格像这样放在div里面，使表格垂直滚动。将overflow-y更改为overflow-x，使表可水平滚动。只是溢出使表可以水平和垂直滚动。

<div style="overflow-y: scroll;"> 
    <table>
    ...
    </table>
</div>
