My take is in semantics depending on how you define your container. For example, A "bag of apples" or simply "apples" or an "apple bag" or "apple".
Example:
a "college" table can contain 0 or more colleges
a table of "colleges" can contain 0 or more collegues
a "student" table can contain 0 or more students
a table of "students" can contain 0 or more students.
My conclusion is that either is fine but you have to define how you (or people interacting with it) are going to approach when referring to the tables; "a x table" or a "table of xs"
