Hi

Into cell A5 enter the formula
=IF(B5="","",ROW()-4)
or
=IF(AND(B5="",A6=""),"",ROW()-4)

The first one leaves row number empty, when there is no entry on row, the
second one numberes all rows until last non-empty one.
Instead B5="" you can have some other entry existence check for row 5 -
depending on your table setup. P.e. like this
=IF(AND(COUNTA($B5:X5)=0,A6=""),"",ROW()-4)

Copy the formula down for any reasonable amount of rows

I have an excel sheet that has the title row as the first row. The rows
containing the data can start upto 5 rows below the title row leaving
blank rows in between. I want to insert a column as the first column
containing line numbers for the rows with the data. The line numbers
have to start from the row where the data exists leaving the above
blank rows. Is it possible to do this programmatically using C#. I
tried using an identity column but it didn't work. The error says
"Invalid Operation". Please help! Thanks in advance.
