# Function: column\_pin()

```ts
function column_pin<TFeatures, TData, TValue>(column, position): void;
```

Defined in: [features/column-pinning/columnPinningFeature.utils.ts:56](https://github.com/TanStack/table/blob/main/packages/table-core/src/features/column-pinning/columnPinningFeature.utils.ts#L56)

Moves this column's leaf column ids into a pinning region.

Pinning a group column pins all of its leaves. The leaf ids are first removed
from both regions, then appended to the requested `'left'` or `'right'`
region. Passing `false` unpins them back to the center.
