How to put series of number in excel while filters applied?

[bhanu reakha]

1. I applied filters in my excel
2. I need to put series of number
3. By using this " =COUNTIF(Z$1:Z19,"<>") " formula we can able to fill the
number series when the filters are applied for the excel. But this working
fine when we drag the same for the rest of the rows
4. I need a solution for the same scenario when we double click on the right
corner of the selected cells (to autofill the number series for the remaining
cells instead of draggging)

If I understand what you want...sequentially number a filtered list...

Try this:

=SUBTOTAL(3,Z$1:Z1)

Copy down to the last row of unfiltered data.
