I have a list that where I add info that are then summed up in each column.
Problem I have is that I have to add new rows after filled rows to Row 19
To add a row function. No probs to do that manually. But I want to do it
automatically. It does not matter.
Is it possible?

Row 1 One Two Three
Row 2 Four Five Six
Row 3 Seven Eight Nine
Row 4
Row 5
Row nn
Row19
Row 20 Add Column A Add column B Add column C
