Cell attrs and props are not re-rendering tds reactively

[lolcabanon]

Problem

When a column alignment change, the corresponding th update, but all td stays the same.

Repro

1. Run the project (pnpm dev) and navigate to http://localhost:5173/simpletable
2. Click on alignment buttons on any columns
3. th alignment changes, but tds are stuck in initial state

Troubleshoot

• Initial values are applied with success (play with config to see)
• Derived callbacks re-run as expected (recompute props and attrs) when the columnsAlignments store is updated by toggle
• props and attrs are correctly computed for ths and tds (console.log() in the .update() callback show correct values)
• Tried with {#key} blocks on many values, but nothing seems to trigger a re-render for the table body

Hey @bryanmylee, this is the repo for the plugin I submitted a PR for earlier (couple weeks ago) on svelte-headless-table.

I'm currently stuck on this issue, either I don't understand derived stores, or there is something weird happening... I know you wrote you don't have a lot of time, but if by any chance you have any insight on this, I'd be very grateful!

I looked at your code, mostly the addResizedColumns() plugin that has a similar logic (apply and update inline style in reaction to events), and nothing seems to be too different... It's bugging me so much!
