Return to Question

This code is an academic example, I was trying to write something easy because the domain is not important, but the principles and best practices.

In this code I have a class - Table. It has private array (of objects Cell) which is used by many public functions in the code. BUT there is no function that will return particular cell. So the problem I have, is how can I test Reset function? I can call this function, but I can't review its result. Specially with the Option 2 where I don't have any references to this Array.

That makes me thinking if the design is correct.. and that lead me here.

My questions are:

1. Do I violate any SOLID principle?
2. Is the option 2 better way to go? (although in that case, there's no way to test it

Here's the code:
