区间范围计算
方法一:用IF函数
方法二:构建一个辅助区域，用VLOOKUP函数
方法一:用IF函数
在F3中输入:=IF(E3>=90%,5%,IF(E3>=80%,4%,IF(E3>=70%,3%,IF(E3>=60%,2%,1%))))
向下拖动,搞定。
示例：
=IF(BB2<=0.5,"50及以下",IF(AND(BB2>0.5,BB2<=0.6),"50-60",IF(AND(BB2>0.6,BB2<=0.7),"60-70",IF(AND(BB2>0.7,BB2<=0.8),"70-80",IF(AND(BB2>0.8,BB2<=0.9),"80-90","90以上")))))
