因存在位置未知的空值，需要两两空值判断再进行比较，所以5列两两相比有10种可能，需要全面考虑，缺一都可能导致数据不准确（空值位置影响）
一、初始版本：案例中当前单元格的函数：=AND(IF(OR(B3="",C3=""),TRUE,B3=C3),IF(OR(C3="",D3=""),TRUE,C3=D3),IF(OR(D3="",E3=""),TRUE,D3=E3),IF(OR(E3="",F3=""),TRUE,E3=F3),IF(OR(B3="",F3=""),TRUE,B3=F3),IF(OR(B3="",D3=""),TRUE,B3=D3),IF(OR(B3="",E3=""),TRUE,B3=E3),IF(OR(C3="",F3=""),TRUE,C3=F3),IF(OR(C3="",E3=""),TRUE,C3=E3),IF(OR(D3="",F3=""),TRUE,D3=F3))
注意：使用此方法前请根据实际需要同时比较的列数，进行排列组合，增加或减少比较种类的数量（即if的数量）
一、升级版本：
=IF(AND(IF(OR(B3="",C3=""),TRUE,B3=C3),IF(OR(B3="",F3=""),TRUE,B3=F3),IF(OR(B3="",D3=""),TRUE,B3=D3),IF(OR(B3="",E3=""),TRUE,B3=E3)),"",$B$2&":"&B3)
&" "&IF(AND(IF(OR(B3="",C3=""),TRUE,B3=C3),IF(OR(C3="",D3=""),TRUE,C3=D3),IF(OR(C3="",F3=""),TRUE,C3=F3),IF(OR(C3="",E3=""),TRUE,C3=E3)),"",$C$2&":"&C3)
&" "&IF(AND(IF(OR(C3="",D3=""),TRUE,C3=D3),IF(OR(D3="",E3=""),TRUE,D3=E3),IF(OR(B3="",D3=""),TRUE,B3=D3),IF(OR(D3="",F3=""),TRUE,D3=F3)),"",$D$2&":"&D3)
&" "&IF(AND(IF(OR(D3="",E3=""),TRUE,D3=E3),IF(OR(E3="",F3=""),TRUE,E3=F3),IF(OR(B3="",E3=""),TRUE,B3=E3),IF(OR(C3="",E3=""),TRUE,C3=E3)),"",$E$2&":"&E3)
&" "&IF(AND(IF(OR(E3="",F3=""),TRUE,E3=F3),IF(OR(B3="",F3=""),TRUE,B3=F3),IF(OR(C3="",F3=""),TRUE,C3=F3),IF(OR(D3="",F3=""),TRUE,D3=F3)),"",$F$2&":"&F3)
思路：跟当前彩票站有关的对比放一起，若其中一个有差异即返还当前彩票站比例，逐一彩票站返回即可（空值为无差异的项目）
