Hi Luisa,
This can be achieved based on your context binding to the V1 table element.
If you bind the view context node to the V1 table element, you can achieve this by declaring a global component attribute and update this attribute with the added entries in V2. Add the contents of this attribute to V1 context node.
If you bind the component controller context node to the V1 table element, you can achieve this by updating this node with the added entries in V2.
Thanks,
Vamshi
