How to write test cases for identical screens?

Question

Software testing

There are two screens. In nav we have two different links, for example: P-1, P-2 - these are two very similar screens.
These screens have a completely identical element, a table with columns COL-1, COL-2, COL-3
Our task is to check the presence of columns in these two tables.
The question is this: Are we splitting the check for the presence of these columns into two different cases, or are we writing everything in one?
Or something different?
