# SortFnDef

# Interface: SortFnDef\<TFeatures, TData\>

Defined in: [features/row-sorting/rowSortingFeature.types.ts:58](https://github.com/TanStack/table/blob/main/packages/table-core/src/features/row-sorting/rowSortingFeature.types.ts#L58)

The definition object accepted by `constructSortFn`.

`sort` is a value-level comparator: it receives both rows' (resolved) data
values instead of the whole rows, so normalization concerns stay in
`resolveDataValue`.

## Extended by

## Type Parameters

### TFeatures

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

### TData

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

## Properties

### resolveDataValue?

```ts
optional resolveDataValue: TransformDataValueFn;
```
