Sort PowerBI Matrix table

Hi,

I am trying to sort a matrix table in number order, however it is a survey, so the matrix looks like this for column one as they are questions

1. How good are the.... ?

10. How clear were ...?

This continues up to

19. How well...?

Then jumps back to Question 2

2.

20.

21.

I have tried an index to sort, tried adding another column and sorting but just seem impossible and I am wasting so much time google and checking google and forums and there doesn't seem to be any correct answer that work.

Any ideas?

Thanks
