Tanstack Table breaks on newer Svelte versions #6153
Description
TanStack Table version
8.21.3
Framework/Library version
Svelte 5.46.4
Describe the bug and the steps to reproduce it
Hello from the other side,
we ran into an issue where Tanstack table performance was very poor. We had the same issues with different data sizes (for example 5k or 30k, both performed very poorly even tho the 5k was a little better).
The performance problems happened on:
- initial rendering of the table
- sorting
- filtering
Basicly any time the getRowModel() gets recalculated, it gets stuck in super long calculations.
What we found out is, that this behaviour only breaks on newer Svelte versions. We then downgraded our Svelte version again and everything worked just fine.
old working version: svelte@5.38.10
after upgrading (where the performance problems happen): svelte@5.46.4
We didn't investigate which version specifically introduced the issue.
