    public FileResult Export(string GridHtml)
    {
        using (MemoryStream stream = new System.IO.MemoryStream())
        {
            StringReader sr = new StringReader(GridHtml);
            Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);
            PdfWriter writer = PdfWriter.GetInstance(pdfDoc, stream);
            pdfDoc.Open();
            XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);

The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:

<table id="example" class="display nowrap" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Age</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </thead>
        <tfoot>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Age</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </tfoot>
        <tbody>
            <tr>
                <td>Tiger Nixon</td>
                <td>System Architect</td>
                <td>Edinburgh</td>
                <td>61</td>
                <td>2011/04/25</td>
                <td>$320,800</td>
            </tr>

                <td>San Francisco</td>
                <td>66</td>
                <td>2009/01/12</td>
                <td>$86,000</td>
            </tr>
            <tr>
                <td>Cedric Kelly</td>
                <td>Senior Javascript Developer</td>
                <td>Edinburgh</td>

    </table>

The Javascript shown below is used to initialise the table shown in this example:

$(document).ready(function() {
    $('#example').DataTable( {
        dom: 'Bfrtip',
        buttons: [
            'copy', 'csv', 'excel', 'pdf', 'print'
        ]
    } );
} );

The following CSS library files are loaded for use in this example to provide the styling of the table:
