Solution:
Use SPL XLL to enter the formula below:
=spl("=t=?.group@i(!~.ifn()),k=1,t.run(t1=~(k)(2),t6=~(k+1)(2),~.m(3+k:).run(~(1)=t1,~(6)=t6),k=2),t.conj()",A1:F29)
As shown in the picture below:
Explanation:
group@i()function groups rows according to the specified condition; ifn() function returns the first non-null member; ~ represents is the current member and ~(6) represents the 6th member on the current member’s subordinate level; and m(i:) gets members from the ith to the last one.
