如何在我的SAP UI5 SmartTable中启用过滤？

<mvc:View xmlns:mvc="sap.ui.core.mvc" xmlns="sap.ui.comp.smartfilterbar" xmlns:smartTable="sap.ui.comp.smarttable">

    "use strict";

    return Controller.extend("myController", {
        onInit: function() {
            this._oSmartTable = this.getView().byId("mySmartTable");
            this._oSmartFilterBar = this.getView().byId("mySmartFilterBar");

            this._oSmartTable.setSmartFilterId(this._oSmartFilterBar.getId());
        }
    });
});
