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>

不需要用div包装它…

CSS:

tr {
width: 100%;
display: inline-table;
table-layout: fixed;
}

table{
 height:300px;              // <-- Select the height of the table
 display: block;
}
tbody{
  overflow-y: scroll;      
  height: 200px;            //  <-- Select the height of the body
  width: 100%;
  position: absolute;
}

迟到的派对(我的生活的故事)，但由于这是谷歌上的第一个结果，上面没有一个让我工作，下面是我的代码

/*Set a min width where your table start to look like crap*/
table { min-width: 600px; }

/*The next 3 sections make the magic happen*/
thead, tbody tr {
    display: table;
    width: 100%;
    table-layout: fixed;
}

tbody {
    display: block;
    max-height: 200px;
    overflow-x: hidden;
    overflow-y: scroll;
}

td {
    overflow: hidden;
    text-overflow: ellipsis;
}

/*Use the following to make sure cols align correctly*/
table, tr, th, td {
    border: 1px solid black;
    border-collapse: collapse;
}


/*Set your columns to where you want them to be, skip the one that you can have resize to any width*/
    th:nth-child(1), td:nth-child(1) {
    width: 85px;
}
th:nth-child(2), td:nth-child(2) {
    width: 150px;
}
th:nth-child(4), td:nth-child(4) {
    width: 125px;
}
th:nth-child(5) {
    width: 102px;
}
td:nth-child(5) {
    width: 85px;
}

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>

<style>

thead, tbody

   overflow: auto;
   height: 100px;

</style>

<table class="table table-bordered table-striped">
    <thead style="background-color:lightgreen">
        <tr>

        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>

        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
        <tr>
            <td>1</td>
            <td>Shahriar</td>
            <td>12</td>
        </tr>
    </tbody>
</table>

我使用floatThead jQuery插件(https://mkoryak.github.io/floatThead/#intro)

文档说它适用于Bootstrap 3表，我可以说它也适用于Bootstrap 4表，有或没有表响应帮助。

使用插件就像这样简单:

HTML(普通引导表标记)

<div class="table-responsive">
   <table id="myTable" class="table table-striped">
        <thead>...</thead>
        <tbody>...</tbody>
   </table>
</div>

插件初始化:

$(document).ready(function() {
    var tbl=$('#myTable');
    tbl.floatThead({
        responsiveContainer: function(tbl) {
            return tbl.closest('.table-responsive');
        }
    });
});

完整的免责声明: 我没有以任何方式与插件相关联。在尝试了这里和其他地方发布的许多其他解决方案后，我碰巧发现了它。
