Job ID: 36485238

Budget: $10 – $30 USD

I need to add in a column the number of rows and in another column a formula in Excel. I am using the PhpSpreadsheet library.

The data is already exported to Excel from MySQL, but when adding the number of rows and the formula it shows an error.

The formula of go =SUM(D2:F2), where D2:F2 the number "2" must change according to the rows of all the records, that is to say that the number "2" must not be kept static.

He sent the files.
