Stable / multi-column table sort (sort by secondary column, then primary)

Hi team, first of all thanks a lot for the continuous work on tables — they've become really pleasant to use, and single-column sorting already works well, including numeric ordering of IP addresses within one subnet (sorting an IP column correctly puts 192.168.69.9 before 192.168.69.10). The one thing I'm missing is a two-level sort. I keep an IP/host inventory that I'd like ordered by VLAN (primary) and by IP (secondary) within each VLAN. The usual workaround — sort by the secondary key (IP) first, then the primary key (VLAN) — doesn't hold: after sorting by VLAN, the IP order within each VLAN group gets scrambled again. This suggests the column sort isn't stable, so sorts can't be chained to build a multi-key order. Either of these would solve it: make column sort stable, so sorting one column and then another produces a true multi-key result, or add an explicit multi-column sort (choose a primary + secondary column). As a small bonus: when …
