其中1<=C6/D6<2这样的表达方式不被认可,而且第一个IF中已经包含<1,第二个写成<2就可以了,你先改成
=IF(C6/D6<1,(C6*E6+G6+H6+F6)/C6,IF(C6/D6<2,(C6*E6+G6+H6+F6*2+E6*I6)/C6,IF(C6/D6<3,(C6*E6+G6+H6+F6*3+E6*I6*2)/C6,IF(C6/D6<4,(C6*E6+G6+H6+F6*4+E6*I6*3)/C6,IF(4
IF(C6/D6<1,(C6*E6+G6+H6+F6)/C6,IF(AND(C6/D6>=1,C6/D6<2),(C6*E6+G6+H6+F6*2+E6*I6)/C6,IF(AND(C6/D6>=2,C6/D6<3),(C6*E6+G6+H6+F6*3+E6*I6*2)/C6,IF(AND(C6/D6>=3,C6/D6<4),(C6*E6+G6+H6+F6*4+E6*I6*3)/C6,IF(C6/D6>=4,"")))))
