To clarify this answer. Tables loaded from the backend TQL are owned by the user: Administrator Super-User. When you access tables via the front-end client the following applies:
- If you are a member of the administrators group you have authorisation to all tables.
- If a table has been explicitly shared with you, you have authorisation to the table
- If you own the table, i.e. uploaded via client file upload.
I assume you are not a member of the administrators group. Therefore as part of table creation you will need to have an administrator share this table appropriately or become a member of the administrators group.
