## Type definition

A question mark (?) marks an optional field; readonly marks a value you should not change directly. A union (|) accepts one of the listed forms. Functions are callbacks that Grid invokes at the relevant point.

```typescript
export interface RowDataTransaction<TRow = Record<string, unknown>> {
  add?: ReadonlyArray<TRow>;
  addIndex?: number;
  update?: ReadonlyArray<Partial<TRow>>;
  remove?: ReadonlyArray<TRow | Record<string, unknown>>;
}
```
