@alpinemartin. Ok. I am not sure I understand exactly what problems you are having. If you follow the instructions as is, you should get the table to span the page just fine. All you need to do is create a fictious position in the module’s Position setting. It can be anything. Just make it up. I just used ‘x_list’ as an example. Then in the article, you type {loadposition x_list} and that’s it.
Let me know if you have any further questions.
