如何在数据表中添加两个按钮

Answer 1

您只需要按照本文档给出两个对象。 这里

[{ 
extend: 'excel', text: 'export to excel &nbsp; <i class="fa fa-file-excel-o" aria-hidden="true"></i>'
},
{
extend: 'pdf',   text: 'export to pdf &nbsp;   <i class="fa fa-file-excel-o" aria-hidden="true"></i>'
}]

Answer 2

在这里，您将两个按钮包含在一个对象中。尝试这样。

$(document).ready(function() {
$('#example').DataTable({
dom: 'Bfrtip',
buttons: [{
extend: 'pdf',
title: 'Customized PDF Title',
filename: 'customized_pdf_file_name'
}, {
extend: 'excel',
title: 'Customized EXCEL Title',
filename: 'customized_excel_file_name'
}, {
extend: 'csv',
filename: 'customized_csv_file_name'
}]
});
});
