# row_getIsGrouped

# Function: row\_getIsGrouped()

```ts
function row_getIsGrouped<TFeatures, TData>(row): boolean;
```

Defined in: [features/column-grouping/columnGroupingFeature.utils.ts:250](https://github.com/TanStack/table/blob/main/packages/table-core/src/features/column-grouping/columnGroupingFeature.utils.ts#L250)

Checks whether this row was created as a grouped row.

Grouped rows carry a `groupingColumnId`; ordinary leaf rows do not.

## Type Parameters

### TFeatures

`TFeatures` *extends* [`TableFeatures`](../../index/interfaces/TableFeatures.md)

### TData

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

## Parameters

### row
