Open PDF Internet Explorer

Question

Good morning, I need to Open PDF of my table at the click button, it is working in all browsers, except in IE, in principle just convert Base64 into something that IE support, automatic, via javascript, more is what I’m not getting.

this is my JS

gerarRelatorio = function() {
    var doc = new jsPDF('l', 'pt');
    var res = doc.autoTableHtmlToJson(document
            .getElementById("tabela"));

    var header = function(data) {
        doc.setTextColor(40);
        doc.setFontStyle('normal');
        doc.setFontSize(11);    
    };

    var options = {
        addPageContent : header,
        theme : 'striped',
        tableWidth : 'auto',
        margin : {
            top : 80
        },
        startY : false
    };

    doc.autoTable(res.columns, res.data, options);

    var data = doc.output('dataurl');
    var fileName = "pdf.pdf";
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        var byteCharacters = atob('dataurl');
        var byteNumbers = new Array(byteCharacters.length);
        for (var i = 0; i < byteCharacters.length; i++) {
            byteNumbers[i] = byteCharacters.charCodeAt(i);
        }
        var byteArray = new Uint8Array(byteNumbers);
        var blob = new Blob([byteArray], {type: 'application/pdf'});
        var base64EncodedPDF = data;
        var dataURI = "data:application/pdf;base64," + data;
        window.open(dataURI, '_blank');
        window.navigator.msSaveOrOpenBlob(blob, fileName);
        window.open("data:application/pdf;base64, " + dados, '', 
        "height=600,width=800");
    }
    else {
        x = window.open();
        iframe = x.document.createElement('iframe')
        iframe.width = '100%'
        iframe.height = '100%'
        iframe.frameBorder = 0
        dados = doc.output('dataurl');
        iframe.style = "border: 0"
        iframe.src = 'data:application/pdf;base64' + dados
        x.document.body.appendChild(iframe);
    }
}
