Prohibit re-rendering of entire table on row expansion

Describe the bug and the steps to reproduce it

i have a situation where i am rendering a subcomponent on row expansion. this works well and as expected. Unfortunately though the toggle expansion handler seems to render the entire table on a change. this causes a huge amount of unnecessary requests to the server.

I did find this post but it is fairly outdated: https://github.com/TanStack/table/discussions/2212. is it possible to stop the rendering using useMemo or something equivalent? the behavior im after is that i fetch the subcomponent on expansion, but only on expansion. ie if another row is expanded, the refetch should not occur again. if there was only a few rows it wouldnt be a problem, but when we have 10k etc this is an issue.

thanks for the help.
