Solid indeed does not have the same number of options that React has when it comes to UI component libraries. I've only used Solid on small throwaway projects, but I do like it better than React.

However, like you've pointed out, there's going to be things that you have to do yourself that in React you could likely depend on someone else for.

For tables though, I haven't used this in Solid, but it's pretty nice in general https://tanstack.com/table/latest

We are using PrimeVue at my work and are very happy with it. I'm not super familiar with Mui so can't directly compare.
