 *
 * @core
 * @class Core
 * @description
 *
 * The `Handsontable` class (known as the `Core`) lets you modify the grid's behavior by using Handsontable's public API methods.
 *
 * ::: only-for react
 * To use these methods, associate a Handsontable instance with your instance
 * of the [`HotTable` component](@/guides/getting-started/installation.md#_4-use-the-hottable-component),
 * by using React's `ref` feature (read more on the [Instance methods](@/guides/getting-started/react-methods.md) page).
 * :::
 *
 * ## How to call a method
 *
 * ::: only-for javascript
 * ```js
 * // create a Handsontable instance
 * const hot = new Handsontable(document.getElementById('example'), options);
 *
 * // call a method
 * hot.setDataAtCell(0, 0, 'new value');
 * ```
 * :::
 *
 * ::: only-for react
 * ```jsx
 * import { useRef } from 'react';
 *
 * const hotTableComponent = useRef(null);
 *
 * <HotTable
 *   // associate your `HotTable` component with a Handsontable instance
 *   ref={hotTableComponent}
 *   settings={options}
 * />
 *
 * // access the Handsontable instance, under the `.current.hotInstance` property
 * // call a method
 * hotTableComponent.current.hotInstance.setDataAtCell(0, 0, 'new value');
 * ```
 * :::
 *
 * @param {HTMLElement} rootElement The element to which the Handsontable instance is injected.
 * @param {object} userSettings The user defined options.
 * @param {boolean} [rootInstanceSymbol=false] Indicates if the instance is root of all later instances created.

   *  | Action               | With `index` | Without `index` |
   *  | -------------------- | ------------ | --------------- |
   *  | `'insert_row_above'` | Inserts rows above the `index` row. | Inserts rows above the first row. |
   *  | `'insert_row_below'` | Inserts rows below the `index` row. | Inserts rows below the last row. |
   *  | `'remove_row'`       | Removes rows, starting from the `index` row. | Removes rows, starting from the last row. |
   *  | `'insert_col_start'` | Inserts columns before the `index` column. | Inserts columns before the first column. |
