I know that this is not what you asked for exactly, but coupled with 
CELL() or COUNTBLANK() function, might allow you to establish the row 
number in your situation.

The following allows me to get the last value of the column (F) in 
sheet1 (used in my case in a summary table that lists the final value in 
a column that lists the running balance of my bank account)...

=OFFSET($'sheet1'.$F$6,COUNTA($'sheet1'.$F$6:$'sheet1'.$F$9633)-1,0)

Assumes the range $F$6: to $F$9633 has continuous data - essentially it 
returns the number of rows/cells with data, so will not work if your 
array or range has blanks (unless the number is static or can be predicted).

So in your example... COUNTA(A1:A1000) will return 4, knowing that you 
start from A1 allows you to extrapolate that the last row is A4.
