@Serhioromano In short no. : )
The table I have rewritten from scratch there are too many things missing for me or was at the time. (But I am not using it after all because I am not using tables at all with my current project)
With the tree I have tried to recreate the look of a tree with the https://quasar.dev/vue-components/expansion-item. And it sort of worked : ) But it was way too slow … So I am not using that either. I still have to solve this issue (I am working on something else just now)
I ended up creating a feature request because I thought it would benefit everyone:
