=SUM(Sheet2! A2:A7)  =SUM(Sheet2! A2:Sheet2! A7)  =SUM((Sheet2)A2:A7)  =SUM((Sheet2)A2:(Sheet2)A7)  
V=6/H(A1+ 4A0 +A2)  V=4/H(A1+A0 +A2)  V=6/H(A 1+A 0 +A2)  V=4/H(A 1+ 4A0 +A2)  
=SUM(Sheet2!A2:A7)  =SUM(Sheet2!A2:Sheet2!A7)  =SUM((Sheet2)A2:A7)  =SUM((Sheet2)A2:(Sheet2)A7)  
F={A1→A2,A1→A3}   F={A1→A2}   F={A1→A2}   F={A1A3→A2,A1A2→A3}  
=SUM(A2:A5)  =SUMIF(A2:A5,800,B2:B5)  =COUNTIF(A2:A5,800)  =SUM(B2:B5,800,A2:A5)  
=AVERAGE(A2:H2)  =SUM(A2:H2)  =SUM(A2:H2)-MAX(A2:H2)-MIN(A2:H2)  =(SUM(A2:H2)-MAX(A2:H2)-MIN(A2:H2))/(COUNT(A2:H2)-2)  
SUM(A2:A6)  A2+A3+A4+A5+A6  =SUM(A2:A6)  =SUM(A2,A6)  
如果A1=90、A2=人数、A3=…""、A4=54、A5=36,则公式"=Count(A1:A5)"返回5  如果A1=6.28、A2=3.74,其余单元格为空,则公式"=Counta(A1:A7)"的计算结果等于2  如果A1=90、A2=人数、A3=""、A4=54、A5=36,则公式"=Count(A1:A5)"返回3  如果A1=6.28、A2=3.74,其余单元格为空,则公式"=Counta(A1:A7)"的计算结果等于3
