👍 guess ill have to go through and check the apis for these. for another PR though 😄.

I don't think any of the imports you added are supposed to be public.

[MajesticPotatoe]

@KaelWD row, v-simple-checkbox (which seems to be missing from this), and v-list-item-icon i could see being public.
i used v-row and checkbox back in alpha when neko released the tables originally, though those were never really documented.
v-tabs-bar can technically be removed all together as its not used by anything publicly or privately (at least that i could find).
v-list-item-icon is what kinda started all this because apparently a subset of the community used it somehow (even though in 1.5 it didn't seem to be documented).

not sure about some of the other ones for tables though, @nekosaur may have to attest to those.

I suppose better question would be what changed to cause some of these to stop working?

stale

[nekosaur]

v-simple-checkbox should be available. row i'm a bit more ambivalent on, but leaning against no.
