World's most performant web table - Try it!

A multithreaded web table, capable of running 120fps while sorting/filtering/scrolling simultaneously.

Posting updates & soon video walk-through: https://x.com/GabrielPeterss4. DMs are open, curious to hear about use-cases or advise on how to use it :)

The most performant DOM-based grid.

Uses a shared array buffer to store order/filtering of rows, computed in a web worker off-thread
Resuses all part of DOM-tree
Own event loop to prioritize tasks. Never drops a frame, even when filtering millions of rows
Non-passive scrolling. Rows will never be seen rows loading into the UI while scrolling
Custom virtualization and scrolling. Not limited by browsers 15 million pixel div height limit
Custom built scrolling for phones, and runs at 60fps even on older phones

Benchmark	Score
Scroll 40 rows every frame	120fps
Filtering	200ms
Time to initialize grid and show rows	1.5ms
Filter&sort simultaneously every 300ms	120fps

zero copy datatype

iphone safari has a very low memory limit - disable multithreading there
expand synthetic event-loop to include scrolling & rendering cell contents
can maybe make GC be a bit less expensive by reusing cell classes more..
if user zoomed in/out scrollbar will navigate to fast/slow, needs to be relative to the scroll track
sort/filter all columns, not just second lol
resize columns
custom cells (you can kinda already do this though, just add a new cell class)
make sure rows are ordered correctly for text selection
