증분 계산을 사용할 때 SpreadJS는 기간에 따라 셀을 계산하고 기간마다 UI 이벤트를 확인하고 응답합니다.
이렇게 하면 통합 문서에 많은 수식이 포함되어 있을 경우 UI가 장시간 멈추는 현상을 방지할 수 있습니다.
incremental calculation 기능을 사용하려면 통합 문서 옵션 incrementalCalculation을 true로 설정하거나 incrementalCalculation이 있는 파일을 로드해야 합니다. 예:
증분 계산을 사용할 때 사용자는 CalculationProgress 이벤트를 통해 계산 진행률을 확인할 수 있습니다.
예:
