    Hi jsshivalik,

      What is difference in columnDef & aoColumnDefs in Jquery Datatable

    The difference is that aoColumnDefs has a higher priority than columnDefs.

    No matter which attribute you set first, the final rendering effect of the table comes from aoColumnDefs.

    This is the definition of these two parameters :https://datatables.net/reference/option/columnDefs

    https://legacy.datatables.net/usage/columns

    In fact ,there is no substantial difference between them, their purpose is to set the column properties of the table.

    I have made an example about these two parameters:

    <!DOCTYPE html>
    
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
        <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.19/css/jquery.dataTables.css" />
        <script src="https://code.jquery.com/jquery-3.3.1.js"></script>
        <script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.19/js/jquery.dataTables.js"></script>
        <script type="text/javascript">
            $(function () {
                $('#example').DataTable({
                    aoColumnDefs: [
                        { targets: [0, 1], visible: false }
                    ],
                    columnDefs: [
                        { targets: [0, 1], visible: true }
                    ],
    
                });
            });
        </script>
    </head>
    <body>
        <form id="form1" runat="server">
            <div style="width: 800px; height: 200px;">
                <table id="example" class="display" style="width: 100%">
                    <thead>
                        <tr>
                            <th>Name</th>
                            <th>Position</th>

                            <th>Start date</th>
                            <th>Salary</th>
                        </tr>
                    </thead>
                    <tbody>
                        <tr>
                            <td>Tiger Nixon</td>

                        <tr>

                            <td>$170,750</td>
                        </tr>
                      
                    </tbody>
                    <tfoot>
                        <tr>
                            <th>Name</th>
                            <th>Position</th>
                            <th>Office</th>
                            <th>Age</th>
                            <th>Start date</th>
                            <th>Salary</th>
                        </tr>
                    </tfoot>
                </table>
            </div>
        </form>
    </body>
    </html>
    

    The result of this work demo:
