Hi @klemon,
Currently spaces doesn’t store information about which furniture is inside them and neither the other way around, so there is no easy way to achieve that.
What you can do however is to use this python script from this thread (Space Tagger - Tagging a furniture with the space name) to add a tag to each furniture with the name they are in:
vaSpaceTagger.py (2.7 KB)
Then use the tag property of the furniture to sort them in the data table.
Kind regards
