Multiple columns with nested grids

Hi everyone!

Im trying to figure out how I might be able to do somethinfg similar to this.

Getting the basic single nested grid layout seemed fairly easy, thanks to Pablos excellent examples, but to do multiple columns it looks like you have to configure a “detailCellRenderer” per column, and sadly thats where I run out of talent.

Is this even possible with st-aggrid ? If so, and its been done before, I dont suppose some kind soul could provide an example ?
