如何在从数据表导出的 excel 文件中添加 page_header 和 page_footer 部分，以便在打印文档时页眉和页脚位于每一页中？
不带页眉、页脚的导出excel的当前打印 View :
我想要的带有 page_header、page_footer 的打印 View :
这是我的示例代码:
<html>
<head>
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.23/css/jquery.dataTables.css"/>
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/buttons/1.6.5/css/buttons.dataTables.css"/>
</head>
<body>
<table id="example" class="display" style="width:100%">
<thead>

<th>Position</th>
<th>Office</th>
<th>Age</th>
<th>Start<br />date</th>
<th>Salary</th>

使用此代码，您可以创建页眉和页脚页面。
"buttons": [
{
extend: 'excelHtml5',
text: 'Excel',
customize: function( xlsx ) {
var sheet = xlsx.xl.worksheets['sheet1.xml'];
// Get reference to the worksheet and parse it to xml nodes
// Has to be done this way to avoid creation of namespace atributes.
var afSerializer = new XMLSerializer();
var xmlString = afSerializer.serializeToString(sheet);
var parser = new DOMParser();
var xmlDoc = parser.parseFromString(xmlString,'text/xml');
//Create header and add it to the worksheet
var headerFooter = xmlDoc.createElementNS('http://schemas.openxmlformats.org/spreadsheetml/2006/main','headerFooter');
sheet.getElementsByTagName('worksheet')[0].appendChild(headerFooter);
var nodeHeaderFooter = sheet.getElementsByTagName("headerFooter");
//Creation of the header
var oddHeader = xmlDoc.createElementNS('http://schemas.openxmlformats.org/spreadsheetml/2006/main','oddHeader');
nodeHeaderFooter[0].appendChild(oddHeader);
var nodeOddHeader = sheet.getElementsByTagName("oddHeader");
//The header/footer column definitions
// If unwanted, you can skip a column
//&L = Left column
//&F = Filename
//&A = sheetname
//&C = Center column
//&D = Date
//&T = Time
//&R = Right Column
//&P = Pagenumber
//&N = Total number of pages
var txtHeader = "&L"+"&F - &A"+"&R"+"&D - &T";
var nodeHeader = xmlDoc.createTextNode(txtHeader);
nodeOddHeader[0].appendChild(nodeHeader);
//Creation of the footer
var oddFooter = xmlDoc.createElementNS('http://schemas.openxmlformats.org/spreadsheetml/2006/main','oddFooter');
nodeHeaderFooter[0].appendChild(oddFooter);
var nodeOddFooter = sheet.getElementsByTagName("oddFooter");
var txtFooter = "&R"+"Page &P of &N";
var nodeFooter = xmlDoc.createTextNode(txtFooter);
nodeOddFooter[0].appendChild(nodeFooter);
//Add header and footer to the worksheet
sheet.getElementsByTagName('worksheet')[0].appendChild(headerFooter);
}
}
