Displaying function-backed aggregated values alongside object properties in an Object Table

I have an Object Table in Workshop displaying objects from a dataset. I want to show:

  • A grouping property (e.g. a product name or account name)
  • Aggregated SUM of numeric metrics per group (e.g. total revenue, total quantity)

I have a TypeScript function that computes the top N groups by an aggregated metric and returns the summed values. However:

  1. Object Table only accepts ObjectSet or Osdk.Instance — it can only display properties that exist on the object type, not computed/aggregated values.

What I need:

A table where each row represents a grouped value, showing:

  • The grouping property value

  • Function-computed aggregated metrics

    Is there a supported way to display function-backed aggregated columns in a table widget, or does this require a pre-aggregated object type via a pipeline?
