ARRAYFORMULA not adding to each row

问题

When I add formula to the top of the cell W2

=ARRAYFORMULA(IFNA(if(and(T2:T="",Q2:Q<>""),"VALID","")))

It works fine on that row, however the 2nd row has the same conditions, but it does not say VALID like the 1st row does. When I copy that formula to the 2nd row it shows VALID... So the formula is working, it is not copying down automatically.

回答1:

Since you use the ARRAYFORMULA function you should use * instead of the AND function.

=ARRAYFORMULA(IFNA(IF((T2:T="")*(Q2:Q<>""),"VALID","")))
