如何在if函数中嵌套if函数答:IF(D4>=90,"优",IF(D4>=80,"良",IF(D4>=70,"中",IF(D4>=60,"合格",IF(D4<60,"差"))),或=(IF(D4=90,"优",IF(D4>=80,"良",IF(D4>=70,"中",IF(D4>=60,"合格","差")))
如何用IF语句实现多层嵌套?答:=IF(A1>=100,"A",IF(A1>=90,"B",IF(A1>=80,"C",IF(A1>=70,"D",IF(A1>=60,"E","F")))通过IF函数嵌套,像剥洋葱一样逐层判断A1数值所在的区间,并返回对应的结果。大于等于100,返回“A”,大于等于90,返回“B”,大于等于80,返回“C”……这个公式的优点是易于理解,缺点是...
