I think I understand the confusion.
The Match() function won't do what you're looking for but I'm pretty sure we can get you what you want using Tables->Join on the original tables.

This will combine the two tables by joining rows that have the same value for given columns.
I assume you have tables that look like this.

A table with Courses and Enrollments and another table with Courses and Grades.
Then choose Tables->Join.
Select the table you want to join with.
Then select the columns you want to match and click the "Match" button under the Match Columns section.
Then click OK.

You should get a table like this.

I think that's what you're looking for. It is confusing to think about matching columns and having a Match() function.
You can learn more about the Match() function here.
