具有固定标题的可滚动表

Question

我的表格有5列和几行，tbody是可滚动的， 我的问题是，当我使用colspan在第一个thead行中合并5列时，整个表格的对齐方式都发生了变化， 我该怎么用 如果colspan不在广告中，则工作正常 我需要使用colspan来组合 为此，我遇到了错误

我的代码是

var $table = $('table.scroll'),
$bodyCells = $table.find('tbody tr:first').children(),
colWidth;

//Adjust the width of thead cells when window resizes
$(window).resize(function() {
// Get the tbody columns width array
colWidth = $bodyCells.map(function() {
    return $(this).width();
}).get();

// Set the width of thead columns
$table.find('thead tr').children().each(function(i, v) {
    $(v).width(colWidth[i]);
});    
}).resize(); // Trigger resize handler

wrapper {
    width: 100%;
    float: left;
}
body {
    background-color:#a6e2ff;
}
.scroll table{
    margin: 5% auto auto auto;
    font-size: 16px;
    font-family: inherit;
    border-spacing: 0;
    font-size: 16px;
    border: 2px solid #B7B7B7;
}
.scroll tbody tr:hover {
    background-color: #CECECE;
}
.scroll  td:hover {
    background-color: #f5f5f5;
}
.scroll thead {
    background: #335599;background:linear-gradient(to bottom left,#335599,#335599);
    font-family: sans-serif;
    color: rgb(255, 255, 255);
	height:auto;
}
.scroll td, .scroll th {
    border: 1px solid #B7B7B7;
}
.scroll tr:nth-child(even) {background-color: #f2f2f2}
.scroll td{
    padding: 8px;
}
.scroll th{
    padding: 8px;
}
::-webkit-scrollbar {
display: none;
}
table.scroll tbody,table.scroll thead {
    display: block;
}
thead tr th { 
    height: 30px;
    line-height: auto;
}
table.scroll tbody {
    height: 200px;
    overflow-y: auto;
    overflow-x: hidden;

使用javascript可以创建排序固定的标题。如果可能的话，您需要编写很多代码，所以我更喜欢您可以使用任何易于配置和实现的javascript framework。我在n个项目中都没有使用https://datatables.net/

下面的工作示例，其中包含代码：

$(document).ready(function() {

  var dataSet = [

您是否正在寻找类似的东西？

//Adjust the width of thead cells when window resizes
$(window).resize(function() {

colWidth = $bodyCells.map(function() {
    return $(this).width();
}).get();

// Set the width of thead columns
$table.find('thead tr').children().each(function(i, v) {
    $(v).width(colWidth[i]);
});    
}).resize(); // Trigger resize handler
