# Required Props

```typescript
interface DataEditorProps {
    
    // ... other props

    columns: readonly GridColumn[];
    getCellContent: ((cell) => GridCell);
    rows: number;
    
    // ... other props
}
```

***

### columns

```ts
columns: readonly GridColumn[];
```

`columns` is an array of objects of type `GridColumn` describing the column headers. The length of the array is the number of columns to display. 

> 💡 This value should be memoized so as to avoid extraneous rerendering.

***

### rows

```ts
rows: number;
```

`rows` is the number of rows to display.

***

### getCellContent

```ts
getCellContent: (cell: Item) => GridCell;
```

`getCellContent` returns an object of type `GridCell` describing the contents for the cell at the given coordinates.

> 💡 This value should be memoized so as to avoid extraneous rerendering. This is usually done using `React.useCallback`. Failure to ensure proper memoization will result in slow path rendering at all times.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.grid.glideapps.com/api/dataeditor/required-props.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
