Maybe you could explain more thoroughly what you’re trying to do and how you’re populating the repeater.
When I’ve used a table within a repeater, it’s always to display another collection’s data that is tied to the current repeater row where there is a one-to-many relationship. For instance, I have a volunteer scheduling app where the various committees are listed in each repeater row. The schedule for each committee (data from another collection) appears below the name of the committee.
If you’re displaying data from only one collection, you could just use text elements to display the seven fields’ data.
