# FilterFnDef

# Interface: FilterFnDef\<TFeatures, TData\>

Defined in: [features/column-filtering/columnFilteringFeature.types.ts:97](https://github.com/TanStack/table/blob/main/packages/table-core/src/features/column-filtering/columnFilteringFeature.types.ts#L97)

The definition object accepted by `constructFilterFn`.

`filter` is a value-level comparator: it receives the row's (resolved) data
value and the (resolved) filter value instead of the whole row, so
normalization concerns stay in `resolveDataValue`/`resolveFilterValue`.

## Extended by

- [`CreatedFilterFn`](CreatedFilterFn.md)

## Type Parameters

### TFeatures

`TFeatures` *extends* [`TableFeatures`](TableFeatures.md)

### TData

`TData` *extends* [`RowData`](../type-aliases/RowData.md)

## Properties
