The new table is owned by the user who creates it. The owner of the table is allowed to perform certain operations on the table that other users are not. For example, only the owner (or a user with the security privilege impersonating the owner) can alter or drop a table.

If other users need access to the table, the table owner can grant that permission using table grants. Table grants are enabling permissions—if no permission is granted, the default is to prohibit access.
