## Autonumber rows and skips blank rows by formula

### Formula in cell A2

`=IF(B2<>"",COUNTA(\$B\$2:B2),"")`

For the remaining cells, just copy the formula down.

### How to use the formula

`=IF(First_cell_of_source_list<>"",COUNTA(First_cell_of_source_list(lock row and column):First_cell_of_source_list),"")`

In the sample sheet, the first cell in the source list is cell B2.

“Why is it not cell B1?”

This is because we only count the value in the list but not the column header.

### How does this formula work

`COUNTA(First_cell_of_source_list(lock row and column):First_cell_of_source_list)`

COUNTA function allows us to count the number of cells in a range that are not empty.

Here we are using COUNTA to count the number of non-empty cells between the corresponding cell (here it means the cell next to the cell with formula) and the first cell.

Take cell A5 as an example.

COUNTA functions counts the number of non-empty cells between the corresponding cell (B5) and the first cell in the list (B2). Let’s count it by hand. The number is 3 since there are three non-empty cells (B2, B3 and B5) in the specified range.

`=IF(First_cell_of_source_list<>"",COUNTA(First_cell_of_source_list(lock row and column):First_cell_of_source_list),"")`

IF function allows us to check whether certain conditions are met.

Here IF function help us check whether the corresponding cell is empty. It will only allows COUNTA function to perform if the cell is not empty. If the corresponding cell is blank, the cell will return blank.
