我在让stickytableheaders库工作时遇到了很多麻烦。做了更多的搜索，我发现floatThead是一个积极维护的替代方案，具有最近的更新和更好的文档。

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

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;
}

table { overflow-y: auto; height: 50vh; /* !!! HEIGHT MUST BE IN [ vh ] !!! */ } thead th { background-color: white; position: sticky; top: 0; } <table> <thead> <tr><th>TH 1</th><th>TH 2</th></tr> </thead> <tbody> <tr><td>A1</td><td>A2</td></tr> <tr><td>B1</td><td>B2</td></tr> <tr><td>C1</td><td>C2</td></tr> <tr><td>D1</td><td>D2</td></tr> <tr><td>E1</td><td>E2</td></tr> <tr><td>F1</td><td>F2</td></tr> <tr><td>G1</td><td>G2</td></tr> <tr><td>H1</td><td>H2</td></tr> <tr><td>I1</td><td>I2</td></tr> <tr><td>J1</td><td>J2</td></tr> <tr><td>K1</td><td>K2</td></tr> <tr><td>L1</td><td>L2</td></tr> <tr><td>M1</td><td>M2</td></tr> <tr><td>N1</td><td>N2</td></tr> <tr><td>O1</td><td>O2</td></tr> <tr><td>P1</td><td>P2</td></tr> <tr><td>Q1</td><td>Q2</td></tr> <tr><td>R1</td><td>R2</td></tr> <tr><td>S1</td><td>S2</td></tr> <tr><td>T1</td><td>T2</td></tr> <tr><td>U1</td><td>U2</td></tr> <tr><td>V1</td><td>V2</td></tr> <tr><td>W1</td><td>W2</td></tr> <tr><td>X1</td><td>X2</td></tr> <tr><td>Y1</td><td>Y2</td></tr> <tr><td>Z1</td><td>Z2</td></tr> </tbody> </table>

你不需要js。重要的是设置表格高度[vh]

你应该尝试使用"display:block;"到tbody，因为现在它是内联块，为了设置高度，元素应该是"block"

使用css更容易

table tbody { display:block; max-height:450px; overflow-y:scroll; }
table thead, table tbody tr { display:table; width:100%; table-layout:fixed; }
