Protect cells after Make has entered data

1st q. Happy to be told this is not how its done - like I was at Stack Overflow once.

Can I protect the excel sheet cells which receive the data from the scenario after they are filled?

I can protect the sheet but then Make cant add data to it - I think.

So I guess it needs to protect new lines after they are added (ideally it would only protect a section - E.g. Columns A-F of new lines added).

I tend to use a table in a worksheet as I find it easier to work with.
