I need to hide an open Access table from users
This article at TechRepublic offers two approaches.
One is to set the table as hidden.

Right-click the object in the Database window.
Choose Properties.
Click the Hidden option.

The other is to rename the table.

Another way to hide a table is to add the prefix Usys to the table's name.

Both aren't really secure, as the object is still accessible, but it's not visible at least.
