excel如何根据某一列数值的范围，自动填充内容

Question

例如：如果A1的数值在1~10之间，B1自动填充为AA
如果A1在11~20之间，B1自动填充为BB

Answer 1

=REPT(CHAR(64+ROUNDUP(A1/10,0)),2)

Answer 2

在B1中输入如下公式，然后下增，用if 嵌套实现：
=IF(A1>0,IF(A1<11,"AA",IF(A1<21,"BB","")))

Answer 3

B1单元格写入公式
=IF(A1<1,"",IF(A1<11,"AA",IF(A1<21,"BB","")))
或
=IF(A1="","",LOOKUP(A1,{0,"";1,"AA";11,"BB";21,""}))本回答被网友采纳
