I had this same problem until I realised there is this work around that saves a ton of time.
You can create a copy of the Table then create a copy of the Rows.
You then need to change the type of the table to a Package Form. Click on the Table Name on the left panel on the little drop down triangle, select advanced then select Package Form.
Now you can move the Rows form underneath the Table form.
Click on the Table Form and select the repeating panel.
On the far right-hand panel under properties is a item_template box. It is a tree of all of your forms.
Click on it and select your Rows form.
Voila!
(If you cannot see your Rows form, simply exit your project and return and it will be there)
