Create pagination

Hello, is there any plan to have this feature implemented?

Hey @tmanuel94, there are some features I would like to tackle before as the library can handle pretty large datasets (due to efficient updating of the DOM). Did you try to use the library with a dataset and it was too big for it?

Hi @iddan, I tried with a csv which has 1922 rows * 9 cols and it's just too much to be handled. I don't know if maybe there's something that I can do on my part to have better performance with this kind o f files

Have you tried using the React Dev Tools? You should make sure only the components you expect are rendered?

@iddan I'm not sure on how to implement it as of now, it's a new topic for me. I'll try to look into that! As a tip, do you think that something like an IntersectionObserver could be the way to go?

Not sure. My tip is to use useMemo and useCallback to make sure React is not re-rendering the spreadsheet when not needed.
