假设1-8月份的SHEET中有100行
=SUM(VLOOKUP(Sheet1!B1,Sheet1!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet2!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet3!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet4!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet5!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet6!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet7!A1:E100,5,0),VLOOKUP(Sheet1!B1,Sheet8!A1:E100,5,0))/8
然后拉到A100就可以了。
