Ability to create Form from a Table

Hi I’d like to request a feature to insert a Table into a Form.
Or to allow a Form to show editable pre-defined Table.

This will be very useful in the event when we want others to submit information in the form of a list (for example our dealer/customer to create a list of items they want to order along with the qty and price) without revealing the other pages or the entire doc.

Right now, the Form view can only accept data to create an entry at per row basis. There’s no way to accept data in the form of sub-table (I’ve tried to insert table into a column with Canvas data type as ‘Add new row’s’ value, but the Form view can’t pull the sub-table because the entry hasn’t created yet).

So I kind of hoping there will be a solution for viewer to be able to directly edit a selected table via Form.
