Error- 'TData' is defined but never used.eslint@typescript-eslint/no-unused-vars

[kcalderon37]

Hi,

I'm encountering issues while declaring an interface and receiving errors related to TData and TValue. I followed the same structure as the example below:

import '@tanstack/react-table'

declare module '@tanstack/table-core' {
interface ColumnMeta<TData extends RowData, TValue> {
foo: string
}
}

The issues are like:

"All type parameters are unused.ts(6205)
'TData' is defined but never used.eslint@typescript-eslint/no-unused-vars
'TData' is defined but never used.eslintno-unused-vars
(type parameter) TData in ColumnMeta<TData extends unknown, TValue>"

the only solution for now is adding comment:
// eslint-disable-next-line @typescript-eslint/no-unused-vars, no-unused-vars

Im using version: 8.10.7. Is anyone else experiencing the same issue?

Yes I'm also facing this issue and like you I've had to ignore the issue. It would be nice if we could get this fixed.

I am wondering if any solution to this instead of adding the // eslint-disable-next-line @typescript-eslint/no-unused-vars

Upvoting same for me.
