Might be good to add some tests for it at this point

[jd-solanki]

Unfortunately, I don't know how to write tests 😢

[jd-solanki]

Can't we merge this without that test?

I want to enable these demos: https://anu-vue.netlify.app/guide/components/table.html#filtering

I'm happy to help contribute a test for the updated behavior. Here is a commit that adds tests and removes an unused useMin import: curtgrimes@85e8e13

@jd-solanki Some great resources for writing tests like these are looking at existing tests like this one for useOffsetPagination, and in my opinion GitLab's documentation on tests has some great examples. You can run tests in this project with pnpm test, pnpm test:2 (for running tests under Vue 2), and pnpm test:3 (for running tests under Vue 3). Much of the documentation written for Jest out there will also largely apply to Vitest tests. Hope this helps. Let me know if I can help further!
