<script type="text/javascript">
 $(document).ready(function () {
            $(function () {

                var doc = new jsPDF();
                var specialElementHandlers = {
                    '#toPDF': function (element, renderer) {
                        return true;
                    }
                };
 $('#btnExport').click(function () {

                    var table = tableToJson($('#tblEmpDetails').get(0));
                    var doc = new jsPDF('l', 'pt', 'a1', true);
                    doc.cellInitialize();

                    $.each(table, function (i, row) {
                        doc.setFontSize(15);

                        console.debug(row);
                        $.each(row, function (j, cell) {
                            doc.cell(100, 50, 275, 50, cell, i);
    });
                    });
                    doc.save('sample-file.pdf');

                    for (var i = 0; i < NoOfcolumns - 1; i++) {

                        headers[i] = table.rows[0].cells[i].innerHTML.toLowerCase().replace(/ /gi, '');


                    }

                    // go through cells
                    for (var i = 0; i < table.rows.length; i++) {
                        var tableRow = table.rows[i];

                        }

                        data.push(rowData);
                    }

                    return data;
                }
                //                    doc.save('sample-file.pdf');
