## 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 type CellRenderer<
  TRow = Record<string, unknown>,
  TValue = unknown,
> = (
  input: CellRendererInput<TRow, TValue>,
) => CellRenderOutput;
```
