# BaseGridCell

The `BaseGridCell` represents the common set of items all cells have. A cell is that which is generated from the [`getCellContent`](/api/dataeditor/required-props.md#getcellcontent) callback and is the common language of communication in the `DataEditor`.

```typescript
export interface BaseGridCell {
    readonly allowOverlay: boolean;
    readonly lastUpdated?: number;
    readonly style?: "normal" | "faded";
    readonly themeOverride?: Partial<Theme>;
    readonly span?: readonly [start: number, end: number];
    readonly contentAlign?: "left" | "right" | "center";
    readonly cursor?: CSSProperties["cursor"];
    readonly copyData?: string;
}
```

### allowOverlay

This enables or disables the overlay popup normally triggered by double clicking a cell. Disabling this does not prevent editing. Many cells have a `readonly` property for that.

### lastUpdated

A `performance.now()` relative timestamp that indicates when the cell was last updated. This triggers the `DataEditor` to render a flash of the cells background color indicating an update has happened.

### themeOverride

Overrides the theme of the cell. It is advisable to set your theme overries as high as possible in the tree. Overriding the cell theme is more expensive than a row theme, which is more expensive than a column theme.

### style

`faded` causes the cell to render with a slight transparency.

### contentAlign

A hint to the cell on where to align content. Not all cells respect this yet.

### cursor

An override of the cursor when the mouse is over the cell.

### copyData

Overrides the data the cell will copy into the paste buffer when the user tries to copy the cell.

## 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/cells/basegridcell.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.
