# BaseGridCell

The `BaseGridCell` represents the common set of items all cells have. A cell is that which is generated from the [`getCellContent`](https://docs.grid.glideapps.com/dataeditor/required-props#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.
