函数题目！

=REDUCE(A1:B1,A2:A14,LAMBDA(x,y,IF(y=0,x,VSTACK(x,IF({1,0},y,TOCOL(OFFSET(y,,1,MATCH(,--DROP(y:A16=0,1),-1),3),3))))))

=REDUCE(A1:B1,B2:D10,LAMBDA(x,y,IF(y<>"",VSTACK(x,HSTACK(LOOKUP("々",OFFSET(A1,,,ROW(y))),y)),x)))

学到了。=REDUCE(A1:B1,B2:D14,LAMBDA(x,y,IF(y>0,VSTACK(x,HSTACK(LOOKUP("々",TAKE(A:A,ROW(y))),y)),x)))

=LET(p,B2:D10,HSTACK(TOCOL(IF(p="",坤,SCAN("",A2:A10,LAMBDA(s,n,IF(n="",s,n)))),3),TOCOL(p,3)))
