求助总分等第函数计算
总分前20%为A,中间20%为B,20%为C,20%为D,20%为E,怎么用函数可以直接得出?=LOOKUP(RANK(I2,$I$2:$I$481,0)/480,{0,20,40,60,80}%,{"A","B","C","D","E"}) =MID("ABCDE",MATCH(1=1,PERCENTILE(I$2:I$481,{8,6,4,2,0}*0.1)<=I2,),1) =LOOKUP(I456,PERCENTILE.INC($I$2:$I$480,{0,0.2,0.4,0.6,0.8}),{"e","d","c","b","a"}) =LOOKUP(I456,PERCENTILE.INC($I$2:$I$480,{0,0.2,0.4,0.6,0.8}),{"e","d","c","b","a"}) =LOOKUP(I99,PERCENTILE.INC($I$2:$I$480,{0,0.2,0.4,0.6,0.8}),{"e","d","c","b","a"}) 为啥总消失不见
