Is your feature request related to a problem? Please describe.
we use to enter invoices in teable and each invoice have multiple items so we have to create multple rows with same invoice number

Describe the solution you'd like
if we can have child item support it will be very easier UI and we can manage large data in friendly format

Describe alternatives you've considered
a lot of alternatives we tried which works good with child items

Invoice with child item closed

Invoice row with child item opened

I also tried grouping feature but still it is not robsut and clean as child items

Example
