The excelHtml5 Excel export doesn't work if there is no table footer. The reason seems to be this code in buttons.html5.js:
if ( config.header ) {
xml += addRow( data.footer );
}
It's also not possible to prevent this error by setting the "footer" option to "false" because it only checks for the "header" option. So this won't help:
buttons: [{
extend: 'excelHtml5',
footer: false
}]
When I set the "header" option to "false", it works. But of course the header is also not exported then.
