iOS TableView Cells Append after Button Click

Hey Guys,

i just started working with Xamarin and have a Question about the TableView Object.

Creating a Table View and initialize my Cells as well as fill them works perfectly fine but what I now want to do is following Scenarion:

On App Start I would like to show the first few Cells from Array 1 - the last Cell from Array 1 will be displaying 2 Buttons.
Now what I want to do is wait for the User to Press either Button 1 or Button 2 - if Button 1 was pressed I would like to append a new array - lets call it Array 2 - below the existing one.

Is there a way how to achieve this task?

Thanks you!
