Datatables Warning(table id = 'example'): cannot reinitialise data table

Question

I am working with an example of datatable rowgroup and getting an error like this when loading the page:

Datatables Warning(table id = 'example'): cannot reinitialise data table ##

<script type="text/javascript" language="javascript">
        $(document).ready(function() {
            $('#example').DataTable({
                "processing": true,
                "serverSide": true,
                "ajax": {
                    "url": "tableProcessa.php",
                    "type": "POST"
                }
            });
        });
        
    </script>

    <script type="text/javascript" language="javascript">
        $(document).ready(function() {
            $('#example').DataTable({
                order: [
                    [0, 'asc']
                ],
                rowGroup: {
                    dataSrc: 0
                }
            });
        });
        
    </script>

<table width="100%" class="display" id="example" cellspacing="0">
        <thead>
            <tr>
                <th>OP</th>
                <th>Nome</th>
                <th>Cliente</th>
                <th>Trabalho</th>
                <th>Data</th>
                <th>Obs</th>
            </tr>
        </thead>

The log itself is displaying the error "cannot reinitialise data table", that is, you cannot reboot the DataTable. Start only once and make all necessary settings as in the following example.

<script type="text/javascript" language="javascript">
$(document).ready(function() {
    $('#example').DataTable({
        processing: true,
        serverSide: true,
        ajax: {
            url: "tableProcessa.php",
            type: "POST"
        },
        order: [
            [0, 'asc']
        ],
        rowGroup: {
            dataSrc: 0
        }
    });
});
</script>
