New form designer doesn't allow multiple values for Row labels (can label individual rows in classic designer). Example : You cannot have a table with Sunday - Saturday row label using new form designer.

Also, if you want to fill in a table field with value from a lookup (as a new row option under lookup rules in classic designer) , this option is not available in new form designer.

I believe either of this functionalities haven't been carried over to the new designer. Is there a work around available in new form designer to achieve this?

Thanks in advance.
