Author here. I've used React Table for this, which has like 20k+ stars on Github. It's slow. Imagine you want to edit a cell in a spreadsheet with 40k rows. You MUST create a new array, otherwise React won't update the DOM.

No you just update the cell. React is extremely fast if you understand how rendering works. Avoid unnecessary rerendering of unchanged data.

Have you tried creating your own table in React that supports just your use case? That would've been a fairer comparison un my opinion.

Why should he build his own, you can compare existing things.
