FieldName は特定の DataRecord をフィルター アウトする決定をするために、フィルター条件と一致するセル データを持つフィールド名を指定します。
注： FieldName および Field プロパティは同期されます。FieldName が設定された場合は、Field プロパティは一致する Field オブジェクトを反映するのに更新されます。この名前を持つ Ｆｉｅｌｄ が存在しない場合は、Field プロパティが Null を返します。同じように、Field プロパティを設定することによって、FieldName は Field の名前を反映するのに更新されます。Field が Null に設されている場合は、FieldName も Null に設定されます。
