Table Custom Feature with useReactTable Initial State

[thescripted]

I was following the Guidelines for creating Custom Features, but it seems like when creating a custom feature, the new features does not propagate to table.initialState configurations. This means that the only way to leverage the Density State in this example, would be through table.state and it's associated onChangeFn.

If you take a look at the sandbox: https://tanstack.com/table/v8/docs/framework/react/examples/custom-features?panel=sandbox, and you attempt to apply initialState: { density: "md" } you will get a type-error.

I thought it might have been that I need to extend CompleteInitialTableState with DensityTableState but that did not resolve my issue.

Any guidance? Thank you!
