기본적으로 테이블 시트는 개체의 원격 요청을 구성합니다. 요청을 수동으로 처리하려는 경우 함수의 개체를 바꾸면 데이터 변경 사항이 함수에 전달됩니다.
데이터 변경 세부 정보는 개요의 요청 및 응답 섹션에 있습니다.

Batch 모드
Batch 모드의 요청 처리:
데이터 소스 옵션 변경
표에서 CRUD 옵션 대신 CRUD 함수를 사용하는 경우 이러한 함수는 보안 문제 때문에 JSON 직렬화/역직렬화 후 저장 및 복원할 수 없습니다.
fromJSON 메서드를 호출한 후 표의 데이터 소스 옵션을 설정하면 테이블이 다시 작동할 수 있습니다.
데이터 다시 로드
표의 fetch 메서드가 호출되고 이 메서드의 reload 인수가 true이면 표가 데이터를 다시 로드합니다.
보기의 fetch 메서드는 표의 fetch 메서드와 reload 인수가 동일합니다.
