Question

我想在html表体溢出时添加一个滚动条。我不想滚动表头。我在我的oracle apex页面中有这些html和css代码

HTML

<div class="t-Report-wrap">
<div class="t-Report-tableWrap">
    <table class="t-Report-report" summary="tab">
        <thead>
            <tr>
                <th class="t-Report-colHead" id="CODE" align="center">Code</th>
                <th class="t-Report-colHead" id="HEAD" align="center">Head</th>
            </tr>
        </thead>            
        <tbody>
            <tr> <td > 5198 </td><td >SUSPENCE </td></tr>
            <tr> <td > 1308 </td><td >SHARE IN KNR</td></tr>
            <tr> <td > 4803 </td><td >ONE TIME </td></tr>
            <tr><td >6021</td><td >NEETHI GOODS </td></tr>
            <tr><td >6022</td><td >MANNURE STOCK </td></tr>
            <tr><td >4832</td><td >DONATION TO </td></tr>
            <tr><td >5218</td><td >CALANDER </td></tr>
            <tr><td >4829</td><td >BUILDING TAX </td></tr>
            <tr><td >5199</td><td >BICYCLE ADVANCE </td></tr>
            <tr><td >2509</td><td >BANK LOAN LT MI(SPL) </td></tr>
        </tbody>
    </table>
</div>
<div class="t-Report-links"></div>
<table class="t-Report-pagination t-Report-pagination--bottom" role="presentation"></table> 
</div>

CSS

.t-Report-wrap {
    position: relative;
}
.t-Report-tableWrap {
    height:180px;
    overflow:auto;  
    margin-top:20px;
}
.t-Report-tableWrap table {
    width:100%;
}
.t-Report-tableWrap table thead th .t-Report-colHead {
    position:absolute;   
    top:-20px;
    z-index:2;
    height:20px;
    width:35%;
    border:1px solid red;
}

但是使用此代码，表头也是滚动的。这是从SO回答How to display scroll bar onto a html table引用的。任何人都可以帮我找出这段代码中的错误吗？

Answer 1

更新您的th HTML以包含span：

<th id="CODE" align="center"><span class="t-Report-colHead">Code</span></th>

编辑CSS选择器以删除重复的th：

.t-Report-tableWrap table thead .t-Report-colHead

Answer 2

设置高度并将overflow:auto;添加到.t-Report-tableWrap tbody而不是.t-Report-tableWrap，以便滚动只会影响表格主体。

.t-Report-wrap {
    position: relative;
}
.t-Report-tableWrap {  
    margin-top:20px;
}
.t-Report-tableWrap table {
    width:100%;
}
.t-Report-tableWrap table thead th .t-Report-colHead {
    position:absolute;   
    top:-20px;
    z-index:2;
    height:20px;
    width:35%;
    border:1px solid red;
}
.t-Report-tableWrap tbody{
    height:180px;
    overflow:auto;
}

希望这有帮助。

Answer 3

更改css代码

tbody {
    display:block;
    height:200px;
    overflow:auto;
}
thead, tbody tr {
    display:table;
    width:100%;
    table-layout:fixed;/* even columns width , fix width of table too*/
}
thead {
    width: calc( 100% - 1em )/* scrollbar is average 1em/16px width, remove it from thead width */
}
t-Report-report {
    width:400px;
}

Answer 4

您的代码不正确，因为您在th

中的.t-Report-colHead和.t-Report-tableWrap table thead th .t-Report-colHead {之间添加了额外的空格

但是，这是一个有效的代码。

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

thead{
  display: block;
}

tbody{
  display: block;
  height: 180px;
  overflow: auto;
}
