If this is for the single value type, this could be a configuration rather than a widget. The summary table is an attachment to activate.

When we use this labeled value, we should provide a calculation process, such as order by + top n in the summary table. In this case, every label's values should do avg first, and list them in the specific order.

NOTICE, multiple line values could redefine the labels, we need to use new labels for the summary table
