I have placed two instances of a repeating field on the layout, one to show all 6 repetitions, the other shows only the first repetition.

 

Using "Hide object if.." I have the correct instance of the field showing up as required in form view, but table view only shows the one instance in any condition.

 

Is there any way to achieve the same effect in table view?

Sure but it will cost you an extra table occurrence.  Create another occurrence of your table and join the two tables on the unique primary key.

 

Place your field from original table occurrence and show all repetitions then place your field from the new table occurrence without extending the repetitions.

Brilliant, thank you.
