# row_getUniqueValues

# Function: row\_getUniqueValues()

```ts
function row_getUniqueValues<TFeatures, TData>(row, columnId): unknown;
```

Defined in: [core/rows/coreRowsFeature.utils.ts:50](https://github.com/TanStack/table/blob/main/packages/table-core/src/core/rows/coreRowsFeature.utils.ts#L50)

## Returns
