Hello i've the Error (dataTables.buttons.js?1051:42)
into the file
row# 42 var _dtButtons = DataTable.ext.buttons;

In Vue
"
import $ from "jquery";
import DataTable from "datatables.net";
import jsZip from "jszip";

import "datatables.net-dt";
import "datatables.net-buttons-dt";
import pdfMake from "pdfmake/build/pdfmake";
import pdfFonts from "pdfmake/build/vfs_fonts";

import "datatables.net-buttons/js/buttons.flash.js";
import "datatables.net-buttons/js/buttons.html5.js";
import "datatables.net-buttons/js/buttons.print.js";

"
The order of imports is correctly. DataTable is before buttons.
Why this code don't work?
Thanks
