When we execute this function, it give us message to import JSZip (actually we are not going to Zip it at all)
$("#grid").pqGrid( "exportData", { format: 'xlsx',filename:'pq_excel.xlsx'} );
So we import the latest version of JSZip (
https://stuk.github.io/jszip/)
however, it give us another error
"jszip.js:1474 Uncaught Error: This method has been removed in JSZip 3.0, please check the upgrade guide."
