As far as we know auto numbering will not work in merged cells. If you need to number a column that it is made up of different sized merged cells, when you try to drag the numbering it tries to resize the merge cells as well. Is there a way to number the merged cells without having to manually type the number?

For example, **A1** is header, range **A2:A15** is made up of different sized merged cells, see the following screen shot. How to fill number series in **A2:A15**?

We can use Excel formula to do it.

Step 1. Select the merged cells (in this example, select **A2:A15**).

Step 2. Press **F2**, or click the **Formula Bar**, enter the formula: **=MAX(A$1:A1)+1**.

Step 3. Press **CTRL+ENTER**.

Mohammed says

=MAX(A$1:A1)+1 equals =ROW()-1, and not working as described in the screenshot!

Mohammed says

Sorry!

It’s my fault, I pasted the formula on a column other than “A”.

It works as described.

BAL says

I tried this formula and I got the columns numbered

1

1

2

2

Any help would be appreciated.
