I want to generate excel sheet from datatable.
Here is my HTML table

<table>
            <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></tbody>
</table>

Here is my Javascript

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

});

Here is references I'm adding to my code:

    <script src="https://cdn.datatables.net/buttons/1.1.2/js/buttons.print.min.js"></script>

But I'm getting error like : 'Object doesn't support property or method Datatable'
