# cell_getSelectionStartHandler

# Function: cell\_getSelectionStartHandler()

```ts
function cell_getSelectionStartHandler<TFeatures, TData, TValue>(cell, _contextDocument?): (e) => void;
```

Defined in: [features/cell-selection/cellSelectionFeature.utils.ts:1068](https://github.com/TanStack/table/blob/main/packages/table-core/src/features/cell-selection/cellSelectionFeature.utils.ts#L1068)

Creates a handler that begins a selection at this cell.

Follows `header_getResizeHandler`: the enable check is resolved once outside
the returned closure and guarded again inside it, the document is injectable
for SSR and cross-document rendering, and the document-level `mouseup`
listener is attached here so a drag released outside the table still ends.
