Hi Steffen,
An EC on iPad app is rendered as one pane and it renders it content bit incorrect. For your case you can go for two solutions:
- Split tables in two ECs and embed them as separate facets for iPad
- Use one master table which has field which indicates a type for the item. For Add button create a list modification structure and form, to provide pop-up window.
If you have a s-user in the marketplace you can find following document RESOURCES: Application Guidelines for Mobile Developers
