Datatables warning(table id = ‘example’): cannot reinitialise data table

Try adding “bDestroy”: true to the options object literal, e.g.

$('#dataTable').dataTable({
    ...
    ....
    "bDestroy": true
});

or Remove the first:

$(document).ready(function() {
    $('#example').dataTable();
} );

In your case is the best option vjk.
