Not exactly, but look at topic “OrderTemplate in Table Format” in this article help.appsheet.com - Email Templates
When the Order record is updated it displays the Customer record, followed by a single Order record, followed by all of embedded Order Detail records for that one Order.
That sample workflow template shows how to get the Customer (parent) record from the updated Order (child) record and display the fields of the Customer record.
The sample only display the single updated Order record.
Instead of displaying that single Order record, you would need to write a <> expression to retrieve the list of all child Order records belonging to the Customer record. The <> expression could do this using the Reverse ref in the Customer record because that field contains the list of child Order records.
The <> expression would be followed by the embedded template that displays each to the child Order records.
