How to add CRLF to last line of CSV export?

Is there a way to make the last line of the results of the HTML5 CSV button also have a CRLF after it? For example, if you go to the HTML5 Exports example page at https://datatables.net/extensions/buttons/examples/html5/simple.html and click on the CSV button and save the file and then open it in something like Notepad++, all the lines have a CRLF after them except for the last line. The reason I ask is I have customers who use the CSV button to export a file and then upload that file to a 3rd party vendor. The 3rd party vendor system ignores the last line because there's no CRLF after it like all the other lines.

Thanks,
Matt
