一种没有固定宽度的简单方法:

.myTable tbody{
  display:block;
  overflow:auto;
  height:200px;
  width:100%;
}
.myTable thead tr{
  display:block;
}

源

现在，在onLoad上，调整宽度，只需添加这个jquery脚本:

$.each($('.myTable tbody tr:nth(0) td'), function(k,v) {
    $('.myTable thead th:nth('+k+')').css('width', $(v).css('width'));
});

使用这个链接，stackoverflow.com/a/17380697/1725764，由Hashem Qolami在原始帖子的评论和使用display:内联块，而不是浮动。 如果表也有'table-bordered'类，则修复边界。

table.scroll {
  width: 100%;  
  &.table-bordered {
    td, th {
      border-top: 0;
      border-right: 0;
    }    
    th {
      border-bottom-width: 1px;
    }
    td:first-child,
    th:first-child {
      border-right: 0;
      border-left: 0;
    }
  }
  tbody {
    height: 200px;
    overflow-y: auto;
    overflow-x: hidden;  
  }
  tbody, thead {
    display: block;
  }
  tr {
    width: 100%;
    display: block;
  }
  th, td {
    display: inline-block;

  }
  td {
    height: 46px; //depends on your site
  }
}

然后把td和th的宽度相加

table.table-prep {
  tr > td.type,
  tr > th.type{
    width: 10%;
  }
  tr > td.name,
  tr > th.name,
  tr > td.notes,
  tr > th.notes,
  tr > td.quantity,
  tr > th.quantity{
    width: 30%;
  }
}

固定表头- css

简单位置:粘;上图:0;第th个元素。(Chrome, FF, Edge)

.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>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> </tbody> </table> </div>

对于黏滞的垂直TH和水平TH列(在TBODY内部):

.tableFixHead          { overflow: auto; height: 100px; width: 240px; }
.tableFixHead thead th { position: sticky; top: 0; z-index: 1; }
.tableFixHead tbody th { position: sticky; left: 0; }

.tableFixHead { overflow: auto; height: 100px; width: 240px; } .tableFixHead thead th { position: sticky; top: 0; z-index: 1; } .tableFixHead tbody th { position: sticky; left: 0; } /* Just common table stuff. Really. */ table { border-collapse: collapse; width: 100%; } th, td { padding: 8px 16px; white-space: nowrap; } th { background:#eee; } <div class="tableFixHead"> <table> <thead> <tr><th></th><th>TH 1</th><th>TH 2</th></tr> </thead> <tbody> <tr><th>Foo</th><td>Some long text lorem ipsum</td><td>Dolor sit amet</td></tr> <tr><th>Bar</th><td>B1</td><td>B2</td></tr> <tr><th>Baz</th><td>C1</td><td>C2</td></tr> <tr><th>Fuz</th><td>D1</td><td>D2</td></tr> <tr><th>Zup</th><td>E1</td><td>E2</td></tr> </tbody> </table> </div>

TH边界问题修复

由于不能在平移后的TH元素上正确地绘制边界， 要重新创建和渲染“边框”，使用box-shadow属性:

/* Borders (if you need them) */
.tableFixHead,
.tableFixHead td {
  box-shadow: inset 1px -1px #000;
}
.tableFixHead th {
  box-shadow: inset 1px 1px #000, 0 1px #000;
}

.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; } /* Borders (if you need them) */ .tableFixHead, .tableFixHead td { box-shadow: inset 1px -1px #000; } .tableFixHead th { box-shadow: inset 1px 1px #000, 0 1px #000; } <div class="tableFixHead"> <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> </tbody> </table> </div>

TH粘不工作修复

确保“th”元素的父元素，至少到表元素(包括)，没有设置溢出相关的样式(例如overflow, overflow-x, overflow-y)。

修正表头-使用JavaScript

对于古老的浏览器，你可以使用一点JS并翻译th元素

// Fix table head example: function tableFixHead(evt) { const el = evt.currentTarget, sT = el.scrollTop; el.querySelectorAll("thead th").forEach(th => th.style.transform = `translateY(${sT}px)` ); } document.querySelectorAll(".tableFixHead").forEach(el => el.addEventListener("scroll", tableFixHead) ); .tableFixHead { overflow-y: auto; height: 100px; } /* Just common table stuff. */ table { border-collapse: collapse; width: 100%; } th, td { padding: 8px 16px; } th { background: #eee; } <div class="tableFixHead"> <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> </tbody> </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;
}

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

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>
