Get the last row with data in a specific table column

Question

I have not used Tables before and am having difficulty getting the last row of data in specific columns of the table

For a Range, for column O, I would use lr= ws.Cells(ws.Rows.Count, "O").End(xlUp).row

But on a Table, this gives me the last row of the table which is different from the last row of data for column O

How to get the last row of data for a specified column?
