如何在 Google Sheet 公式中使用自动填充？

Question

I have formula to auto fill data like column A. It is no need to hand dragging or auto filling by suggestion.

Here column A is perfectly done. Cell A1 formula as below:

={ "VendorNo"; unique(General!A2:A) }

Cell B1 formula is correct as below:

LOOKUP(VendorStatus!A2,sort(General!A2:A),sort(General!C2:C,General!A2:A,TRUE))

Once cell A1 is done, all A column is real auto filled. All I want is to do is the same effect like cell A1. How can I rewrite B1 formula to auto filled the rest B column value?

PS: I am sorry I couldn't post image above directly because I don't have enough reputation.

Answer 1

try in row 1:

={"event start date"; INDEX(IFNA(VLOOKUP(A2:A, General!A2:C, 3, 0)))} 

or:

={"event start date"; INDEX(IFNA(VLOOKUP(A2:A, 
  SORT(General!A2:C, ROW(General!A2:C), 0), 3, 0)))} 

Answer 2

Try in B1 (assuming your formula gives you the right answer)

={"EventStartDate";arrayformula(if(A2:A="",,LOOKUP(A2:A,sort(General!A:A),sort(General!C:C,General!A:A,TRUE))))}
