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; }

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"

所有六个左右的CSS解决方案都假设一个短表。这些代码应该用几百行的代码进行测试。

在我看来，最好的jQuery插件之一是DataTables。

它也有一个扩展的固定头，它是非常容易实现。

摘自网站:

HTML:

<table id="example" class="display" cellspacing="0" width="100%">
    <thead>
        <tr>
            <th>Name</th>
            <th>Position</th>
            <th>Office</th>
            <th>Age</th>
            <th>Start date</th>
            <th>Salary</th>
        </tr>
    </thead>

    <tfoot>
        <tr>
            <th>Name</th>
            <th>Position</th>
            <th>Office</th>
            <th>Age</th>
            <th>Start date</th>
            <th>Salary</th>
        </tr>
    </tfoot>

    <tbody>
        <tr>
            <td>Tiger Nixon</td>
            <td>System Architect</td>
            <td>Edinburgh</td>
            <td>61</td>
            <td>2011/04/25</td>
            <td>$320,800</td>
        </tr>
        <tr>
            <td>Garrett Winters</td>
            <td>Accountant</td>
            <td>Tokyo</td>
            <td>63</td>
            <td>2011/07/25</td>
            <td>$170,750</td>
        </tr>
        <tr>
            <td>Ashton Cox</td>
            <td>Junior Technical Author</td>
            <td>San Francisco</td>
            <td>66</td>
            <td>2009/01/12</td>
            <td>$86,000</td>
        </tr>
  </tbody>
</table>

JavaScript:

$(document).ready(function() {
    var table = $('#example').DataTable();

    new $.fn.dataTable.FixedHeader( table );
} );

但是你可以用最简单的方法来创建一个scrollable <tbody>:

//configure table with fixed header and scrolling rows
$('#example').DataTable({
    scrollY: 400,
    scrollCollapse: true,
    paging: false,
    searching: false,
    ordering: false,
    info: false
});

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

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;
}
