Right-click the relevant table definition and select
Delete Table Instance.
Tip: You can select multiple table instances to delete by holding the
SHIFT key when clicking. Only items under the same table definition can be selected at once.
Note: If you do not have privileges to create a table instance for that definition, you are also unable to delete one, and the option
is not displayed. You must get the catalog owner or another administrator with grant privileges on that table definition to
grant the
Create privilege.
