Building a flow that writes to an excel table. Trying to find a way to determine the next empty cell in Column A of that table so I can write data to the row that corresponds with that cell. What would be the easiest way to accomplish this?

If you use the "add a row into a table" action, it will automatically add a new row to the table. Is that the goal?
