 *
 * const MyComponent = () => (
 *      <DataTable.Row>
 *        <DataTable.Cell numeric>1</DataTable.Cell>
 *        <DataTable.Cell numeric>2</DataTable.Cell>
 *        <DataTable.Cell numeric>3</DataTable.Cell>
 *        <DataTable.Cell numeric>4</DataTable.Cell>
 *      </DataTable.Row>
 * );
 *
 * export default MyComponent;
 * ```
 *
 * If you want to support multiline text, please use View instead, as multiline text doesn't comply with
 * MD Guidelines (https://github.com/callstack/react-native-paper/issues/2381).
