How do I have a vertical line in the second row, between the cells?

I’m getting better at working with this, but I hit the wall with this one. On this page, the second row has two cells with info, and there should be a line between them. But, I don’t have a clue how to do it.
If you show me how, I’ll learn, and expand what I’m able to self-do!
Thank you!
