order: 'applied'
},
},
doc['footer']=(function(page, pages) {
return {
columns: [
'Left part of footer',
{

{ text: page.toString(), italics: true },
' of ',
{ text: pages.toString(), italics: true }
]
}
],
margin: [10, 0]
}
});
]
});
You did not define customize function to dataTable that why getting doc error you need to change您没有为 dataTable 定义自定义函数,为什么会出现需要更改的文档错误
$('#table2').DataTable({
dom: 'Bfrtip',
buttons: [
{
extend: 'pdfHtml5',
text: 'Pdf',
filename: 'dt_custom_pdf',
pageSize: 'A4',
exportOptions: {
columns: ':visible',
search: 'applied',
order: 'applied'
},
customize: function ( doc ) {
doc['footer']=(function(page, pages) {
return {
columns: [
{
alignment: 'center',
text: [
{ text: page.toString(), italics: true },
' of ',
{ text: pages.toString(), italics: true }
]
}
],
margin: [10, 0]
}
});
}
}
]
});
