Lock row within a data table?

[birdec]

I have a data table of students grades. In Row 1 I have the headers, in Row 2 I want "Points Possible" with corresponding numbers in each column.

I want to be able to sort the grades without having the Points Possible row move when I sort it. I've tried Freeze Pane but it still moves when I filter it.

Move the Points Possible row above the table, with a blank row between.
