function exportExcel(id,name){ //<table> id and filename
    var today = new Date();
    var date = ('0'+today.getDate()).slice(-2)+"-"+('0'+(today.getMonth()+1)).slice(-2)+"-"+today.getFullYear();

    var file_name = name+"_"+date+".xls"; //filename with current date, change if needed
    var meta = '<meta http-equiv="content-type" content="text/html; charset=UTF-8" />';
    var html = $("#"+id).clone();

    html.find('.remove').remove(); //add the 'remove' class on elements you do not want to show in the excel
    html.find('a').each(function() { //remove links, leave text only
        var txt = $(this).text();
        $(this).after(txt).remove();
    });
    html.find('input, textarea').each(function() { //replace inputs for their respectives texts
        var txt = $(this).val().replace(/\r\n|\r|\n/g,"<br>");
        $(this).after(txt).remove();
    });
    html.find('select').each(function() { //replace selects for their selected option text
        var txt = $(this).find('option:selected').text();
        $(this).after(txt).remove();
    });
    html.find('br').attr('style', "mso-data-placement:same-cell"); //make line breaks show in single cell
    html = "<table>"+html.html()+"</table>";

    var uri = 'data:application/vnd.ms-excel,'+encodeURIComponent(meta+html);
    var a = $("<a>", {href: uri, download: file_name});
    $(a)[0].click();

$("#export_button").click(function(e){
