You can exclude using class names like this:

"aoColumnDefs": [{ "mColumns": false, "aTargets": ["no-export"] }],

Here is similar code I have working in production:

            var oTable = $('#<%= gvComputers.ClientID %>').dataTable({
            "bJQueryUI": true,
            "bStateSave": true,
            "sPaginationType": "full_numbers",
            "aLengthMenu": [[5, 10, 25, 50, 100, -1], [5, 10, 25, 50, 100, "All"]],
            "aoColumnDefs": [
                { "sSortDataType": "dom-text", "aTargets": ["text-sort_fixed"] },
                { "sType": "numeric", "aTargets": ["numeric-sort"] },
                { "sSortDataType": "dom-select", "aTargets": ["select-sort"] },
                { "sSortDataType": "dom-checkbox", "aTargets": ["checkbox-sort"] },
                { "bSearchable": false, "aTargets": ["no-search"] },
                { "bSortable": false, "aTargets": ["no-sort"] }
            ]
        });

I set the classes as needed on my table header, footer and cells dynamically since I do not know what columns the user will remove from their personal view of the data.
