"columns": [
                {"data": "id"}, 
                { "data": null,
                        render: function( data ) {
                        presupuesto= data.cnt - data.cnt_apr;
                        presupuesto = presupuesto.toFixed(2);
                        return presupuesto;
                            }
                                    },
                 ]

I would like to be able to access that value in the null column when I double-click

              $('#tblPrsp tbody').on('dblclick', 'tr', function () {
        var idPrsp = tblPrsp.row( this ).data();
            alert(idPrsp['null']);
            
        });
