What is the best way to show from and to date (DD/MM/YY) in table header column?

I am working on iPad UI which contains a lot of tables and the overall screen has a very limited real estate. In few table columns I am showing few numbers where table header is from and to date, which is in DD/MM/YY format eg:

12/03/18 - 17/03/18

Now because of the less real estate, I am wrapping it in two lines like

12/03/18
17/03/18

I am looking for an intuitive and less space consuming way to show from and to relationship

like:

12/03/18 -
17/03/18

f:12/03/18
t:17/03/18

These are the two ways I can think of, would be great to see few more examples.

Thanks
