Here is a quick code for how you can export the HTML table to Excel with CSS of table.

Introduction

Many times, we have to export the HTML table in Excel file to offline view and more Excel editing work. This turns more tricky when we need the CSS of the table too. Here is the sample application demonstrating the Excel export.

Background

To start with this, you need a little knowledge of JavaScript.

Using the Code

Put the below code in your Head part of the page.

JavaScript

JavaScript
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        var tableToExcel = (function () {
            var uri = 'data:application/vnd.ms-excel;base64,'
                , template = '<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"><head>
                <!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets>
                <x:ExcelWorksheet><x:Name>{worksheet}</x:Name>
                <x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions>
                </x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook>
                </xml><![endif]--></head><body>
                <table>{table}</table></body></html>'
                , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
                , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
                return function (table, name) {
                if (!table.nodeType) table = document.getElementById(table)
                var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
                window.location.href = uri + base64(format(template, ctx))
            }
        })()
    </script> 

In the above code, we are converting the table to the Excel Sheet standard.

Sample HTML Code

HTML
<input type="button" onclick="tableToExcel('testTable', 'W3C Example Table')" value="Export to Excel">
<table id="testTable" summary="Code page support in different versions of MS Windows."
    rules="groups" frame="hsides" border="2">
    <caption>
        CODE-PAGE SUPPORT IN MICROSOFT WINDOWS</caption>
    <colgroup align="center">
    </colgroup>
    <colgroup align="left">
    </colgroup>
    <colgroup span="2" align="center">
    </colgroup>
    <colgroup span="3" align="center">
    </colgroup>
    <thead valign="top">
        <tr>
            <th>Code-Page<br>ID</th>
            <th>Name</th>
            <th>ACP</th>
            <th>OEMCP</th>
            <th>Windows<br>NT 3.1</th>
            <th>Windows<br>NT 3.51</th>
            <th>Windows<br>95</th>
