DataTables提供了以下示例来实现复杂的标头：https://datatables.net/examples/basic_init/complex_header.html
Double header bar$(document).ready(function() {
$('#example').DataTable();
} );
但是，我正在使用JavaScript初始化：
<head>
<script src="//code.jquery.com/jquery-1.12.3.js"></script>
<script src="https://cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"></script>
<link rel="stylesheet" href="https://cdn.datatables.net/1.10.12/css/jquery.dataTables.min.css">

</table> var table = $('#example').DataTable( {
data: myData,
dom: "B<'row'<'col-sm-6'l><'col-sm-6'f>><'row'<'col-sm-12'tr>><'row'<'col-sm-5'i><'col-sm-7'p>>",
columns: [ {
title: "Position",
data: 'position'
}, {
title: "Salary",
data: 'salary'
}, {
title: "Office",
data: 'office'
}, {title: "Extn",
data: 'Extn'},
{title: "Email",
data: 'Email'}],
});
这本身就可以正常工作（例子不包括数据/库），但是现在当我以这种方式实例化DataTables时如何添加复杂的头文件？
答案 0 :(得分：2)
通过在HTML标记中包含thead元素来构建复杂的标头，无论数据源是什么。如果您使用复杂的标题，则无需columns.title。
$(document).ready(function() {
var data = [{"name":"Tiger Nixon","position":"System Architect","salary":"$320,800","start_date":"2011/04/25","office":"Edinburgh","extn":"5421"}];
$('#example').DataTable({
data: data,
columns: [
{ data: "name" },
{ data: "position" },
{ data: "office" },
{ data: "extn" },
{ data: "start_date" },
{ data: "salary" }
]
});
} );<head>
