I am pretty surprised at how custom filtering works in datatables. It seems like i need to define a global filter function like this:

$.fn.dataTableExt.afnFiltering.push(function (oSettings, aData, iDataIndex) { .. });

and then ALL datatables on my page will use that function to filter. This is not acceptable.

What i need is a way to programmatically filter a datatable using a custom filter function. I would expect this function to take a row and return true/false based on some criteria to show/hide that row from the result.

does a way of doing this exist?

/* Custom filtering function which will filter data in column four between two values */
$.fn.dataTableExt.afnFiltering.push(
        function (oSettings, aData, iDataIndex) {
            if ( oSettings.nTable.id === "my_filtering_table" ) {
                var selectCode = document.getElementById('statusSelect').value;
                return filterRow(selectCode, aData);
            }
            else {
                return true;
            }
        }
);
