So exactly the same level as HTML already does? That seems like interpreting their words so charitably it no longer makes sense.

There is no reason for the author to be misleading about Table as a "high level component". There are more than enough examples that fit your definition. Look at the code for dashboard and music and you will see plenty of abstractions on top of the html components. https://monsterui.answer.ai/music/

You should always aim to interpret most charitably, especially wrt a demonstrated good actor. Or perhaps you have a personal bias I’m not aware of (no shade, it just occurred to me while typing).

No, that's not what I mean. I mean "lower level" might be something like an "input" element - not nested; just a single element. Whereas a table might be considered higher-level: it is made of sub-elements.

That was how I interpreted it.
