인덱스 0에 있는 항목은 최상위 그룹을 설명 하 고 인덱스 1의 항목은 다음 수준에 대해 설명 합니다.The entry at index 0 describes the top-level groups, the entry at index 1 describes the next level, and so on. 컬렉션에 있는 항목 보다 많은 그룹화 수준이 있는 경우에는 마지막 항목이 추가 수준에 사용 됩니다.If there are more levels of grouping than entries in the collection, the last entry is used for the extra levels.
