암시적 교차 논리는 많은 값을 단일 값으로 감소시킨다. 사용자는 하나의 값을 반환하기 위해 함수를 강제하여 함수 앞에 @를 추가할 수 있고, 따라서 셀은 하나의 값만 포함할 수 있다. 함수가 단일 값을 반환하는 경우 암시적 교차로는 아무 것도 수행하지 않습니다. (그것이 기술적으로 뒤에서 행해지고 있었더라도). 논리는 다음과 같다:
값이 단일 항목인 경우 해당 항목을 반환하십시오.
값이 범위인 경우 함수와 동일한 행 또는 열에 있는 셀의 값을 반환하십시오.
값이 배열인 경우 왼쪽 위의 값을 선택하십시오.
동적 배열의 등장으로 SpreadJS는 함수에서 단일 값을 반환하는 데만 국한되지 않으므로, 침묵의 암시적 교차는 더 이상 필요하지 않다. 이전 공식이 보이지 않게 암시적 교차로를 트리거할 수 있는 경우, 동적 배열을 활성화한 SpreadJS는 @에서 발생했을 위치를 보여준다.
Note:
암시적 교차 연산자 @는 allowDynamicArray가 참일 때만 유효하다.
