Now I will explain How to How To Export HTML Table To Excel Using jQuery Plugin

So follow the steps to learn How To Export HTML Table To Excel Using jQuery Plugin

Step 1: Create a HTML file with the below code

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
     <style type="text/css">
        body
        {
            font-family: Arial;
            font-size: 10pt;
        }
        table
        {
            border: 1px solid #ccc;
            border-collapse: collapse;
        }
        table th
        {
            background-color: green;
            color: #fff;
            font-weight: bold;
        }
        table th, table td
        {
            padding: 5px;
            border: 1px solid #ccc;
        }
    </style>
</head>
<body>
    <table id="tblStudent" cellspacing="0" cellpadding="0">
        <tr>
            <th>Name</th>
            <th>Age</th>
            <th>Father Name</th>
        </tr>
        <tr>
            <td>Raj</td>
            <td>12</td>
            <td>Satya Raj</td>
        </tr>
        <tr>
            <td>Kumar</td>
            <td>13</td>
            <td>Ram Kapoor</td>
        </tr>
        <tr>
            <td>Salman</td>
            <td>14</td>
            <td>Raj Sharma</td>
        </tr>
        <tr>
            <td>Andrew</td>
            <td>15</td>
            <td>Anil kumar</td>
        </tr>
    </table>
    <br />
    <input type="button" id="btnExporttoExcel" value="Export To Excel" />
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
    <script src="table2excel.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function () {
            $("#btnExporttoExcel").click(function () {
                $("#tblStudent").table2excel({
                    filename: "Your_File_Name.xls"
                });
            });
        });
    </script>
</body>
</html>

Step 2: Create another file "table2excel.js" and paste the following codes:-

//table2excel.js
; (function ($, window, document, undefined) {
    var pluginName = "table2excel",

    defaults = {
        exclude: ".noExl",
        name: "Table2Excel",
        filename: "table2excel",
        fileext: ".xls",
        exclude_img: true,
        exclude_links: true,
        exclude_inputs: true
    };

    // The actual plugin constructor
    function Plugin(element, options) {
        this.element = element;
        // jQuery has an extend method which merges the contents of two or
        // more objects, storing the result in the first object. The first object
        // is generally empty as we don't want to alter the default options for
        // future instances of the plugin
        //
        this.settings = $.extend({}, defaults, options);
        this._defaults = defaults;
        this._name = pluginName;
        this.init();
    }

    Plugin.prototype = {
        init: function () {
            var e = this;

            var utf8Heading = "<meta http-equiv=\"content-type\" content=\"application/vnd.ms-excel; charset=UTF-8\">";
            e.template = {
                head: "<html xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\">" + utf8Heading + "<head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets>",
                sheet: {
                    head: "<x:ExcelWorksheet><x:Name>",
                    tail: "</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>"
                },
                mid: "</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body>",
                table: {
                    head: "<table>",
                    tail: "</table>"
                },
                foot: "</body></html>"
            };

            e.tableRows = [];

            // get contents of table except for exclude
            $(e.element).each(function (i, o) {
                var tempRows = "";
                $(o).find("tr").not(e.settings.exclude).each(function (i, p) {

                    tempRows += "<tr>";
                    $(p).find("td,th").not(e.settings.exclude).each(function (i, q) { // p did not exist, I corrected

                        var rc = {
                            rows: $(this).attr("rowspan"),

                            flag: $(q).find(e.settings.exclude)
                        };

                        if (rc.flag.length > 0) {
                            tempRows += "<td> </td>"; // exclude it!!
                        } else {
