Enter 키를 누르는 대신 Ctrl + Shift + Enter 키를 눌러 수식을 완성하므로 배열 수식을 CSE(Ctrl + Shift + Enter) 수식이라고도 합니다.
SpreadJS는 수식의 배열 상수를 지원합니다. 중괄호({ })를 사용하여 배열 요소를 묶으십시오. 쉼표를 사용하여 행 내의 요소를 구분하십시오. 세미콜론을 사용하여 배열 내의 행을 구분하십시오. 개별 요소는 숫자 값, 텍스트 값, 논리 값 또는 오류 값일 수 있습니다. 예:
setFormula 메서드와 유사하게, setArrayFormula 메서드를 사용하여 배열 수식을 설정할 수 있습니다. 수식 텍스트 상자에는 중괄호({ })로 묶인 배열 수식이 표시됩니다.
