excel表格中的x/y值列表

Question

I have a table in excel that contains values in row 1 x1,x2...xn and values in column A y1,y2...yn. I need to populate column A in another spreadsheet with values "x1/y1", "x1/y2"..."xn/yn". Is there a way to do this without creating a script in VBA? Until now I was using just =Sheet1!A2&"/"Sheet1!&B1 and draging it down and right and then manualy copying results to column A but as the table grows it becomes quite troublesome.

EDIT: Let me rephrase it so it could be more understandable my Sheet1 looks like

| x1 | x2 | ... | xn | 
y1 |    |    |     |    |
y2 |    |    |     |    |
...
yn |    |    |     |    |

now I need to populate column A in Sheet2 so it would look like

x1/y1
x1/y2
...
x2/y1
x2/y2
...
xn/yn

Is it more understandable now?

Answer 1

You can use a couple of Index formula to do this

=IF(ROW() <= COUNTA(Sheet1!$A:$A) * COUNTA(Sheet1!$1:$1), INDEX(Sheet1!$1:$1,INT((ROW()-1)/COUNTA(Sheet1!$A:$A))+2)&"/"&INDEX(Sheet1!$A:$A,MOD(ROW()-1,COUNTA(Sheet1!$A:$A))+2),"")

Starting at Sheet2!A1 and copy down for at least the number of entries in the table. Any excess formula will show blanks.
