When I tried this code, I was not able to get results in IE plus this code only iterates over td, it will skip any th present in your table. I have modified the code to resolve both the issues I was facing:

$(document).ready(function () {
    function exportTableToCSV($table, filename) {

            var $rows = $table.find('tr'),
            tmpColDelim = String.fromCharCode(11),
            tmpHeadDelim = String.fromCharCode(11),
            tmpRowDelim = String.fromCharCode(0),
            colDelim = '","',
            headDelim = '","',
            rowDelim = '"\r\n"',

            csv = '"' + $rows.map(function (i, row) {
                var $row = $(row),
                $cols = $row.find('td');
                $heads = $row.find('th');

                var c = $heads.map(function (k, head) {
                    var $head = $(head),
                    text = $head.text();
                    return text.replace(/"/g, '""');
                }).get().join(tmpHeadDelim);

                var d = $cols.map(function (j, col) {
                    var $col = $(col),
                    text = $col.text();
                    return text.replace(/"/g, '""');
                }).get().join(tmpColDelim);

            return (c+d);

        }).get().join(tmpRowDelim)
            .split(tmpRowDelim).join(rowDelim)
            .split(tmpHeadDelim).join(headDelim)
            .split(tmpColDelim).join(colDelim) + '"';


        var ua = window.navigator.userAgent;
        var msie = ua.indexOf("MSIE ");

        // if Internet Explorer (10+)
        if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) {
            var blob = new Blob([decodeURIComponent(csv)], {
                    type: 'text/csv;charset=utf8'
            });
            window.navigator.msSaveBlob(blob, filename);
        }
        else {
            var link = document.createElement('a');
            var blob = new Blob([csv],{type:'text/csv;charset=utf8'});
            var url = URL.createObjectURL(blob);
            link.href = url;
            link.setAttribute('download', filename);
            document.body.appendChild(link);
            link.click();
        }
    }

    $("#fnExcelReport").on('click', function (event) {
        var args = [$('#tableContent'), 'Report.csv'];
        exportTableToCSV.apply(this, args);
    });
});
