Nested Tables in table headers and group headers

I would like to use nested tables in table headers and group headers, containing data of a main table other than the current table.

Currently i’m doing this by faking headers and group headers with data rows.

Because of this, i’m losing some benefits of header lines, like keeping headers and data together in case of a page break.

On the backlog for LL24. NB: for group headers, this will work just nicely. For table headers (which are usually repeated on each page) you’ll run into trouble as soon as the content of the nested table exceeds one page. However, these cases will most likely be handled via a separate table in the report container.
