Can you check if calling this causes unnecessary re-renders?

This calls useAtom(contextMenuAtom), which subscribes this component to that atom’s state, so it might cause Table to re-render when the context menu is opened.

We might have to use useUpdateAtom here. The CodeSandbox on this page illustrates what I’m talking about: https://jotai.org/docs/utils/use-update-atom

Note for the future: when we have more context menu actions for different field types, we should move this to src/components/fields/types.ts. I’m also not sure about having this file be inside _BasicCell. This is fine for now however.

I thought setAnchorEle would always exist/never be undefined

You are right. Ill change it

I’m not sure of the benefits of creating custom hooks here, instead of accessing the atoms directly using useUpdateAtom in Table for example

I don't recall where I saw. But I pick up this pattern a while back because it's used to hide the imports

//no custom hook
import { anchorEleAtom } from '@src/store/contextmenu'
import { useAtom } from 'jotai'

const [anchorEle] = useAtom(anchorEleAtom)

//custom hooks

import { useContextMenu } from '@src/store/contextmenu'

const { anchorEle } = useContextMenu()

it's purely syntactic sugar I think. We can remove it if necessary
