Is there a way to disable initial sorting for jquery DataTables?

Well I found the answer set "aaSorting" to an empty array:

$(document).ready( function() {
    $('#example').dataTable({
        /* Disable initial sort */
        "aaSorting": []
    });
})

For newer versions of Datatables (>= 1.10) use order option:

$(document).ready( function() {
    $('#example').dataTable({
        /* No ordering applied by DataTables during initialisation */
        "order": []
    });
})

As per latest api docs:

$(document).ready(function() {
    $('#example').dataTable({
        "order": []
    });
});
