/**
 * @plugin StretchColumns
 * @class StretchColumns
 *
 * @description
 * This plugin allows to set column widths based on their widest cells.
 *
 * By default, the plugin is declared as `'none'`, which makes it disabled (same as if it was declared as `false`).
 *
 * The plugin determines what happens when the declared grid width is different from the calculated sum of all column widths.
 *
 * ```js
 * // fit the grid to the container, by stretching only the last column
 * stretchH: 'last',
 *
 * // fit the grid to the container, by stretching all columns evenly
 * stretchH: 'all',
 * ```
 *
 * To configure this plugin see {@link Options#stretchH}.
 *
 * @example
 *
 * ::: only-for javascript
 * ```js
 * const hot = new Handsontable(document.getElementById('example'), {
 *   data: getData(),
 *   stretchH: 'all',
 * });
 * ```
 * :::
 *
 * ::: only-for react
 * ```jsx
 * const hotRef = useRef(null);
 *
 * ...
 *
 * // First, let's construct Handsontable
 * <HotTable
 *   ref={hotRef}
 *   data={getData()}
 *   stretchH={'all'}
 * />
 * ```
 * :::
 *
 * ::: only-for angular
 * ```ts
 * settings = {
 *   data: getData(),
 *   stretchH: "all",
 * };
 * ```
 *
 * ```html
 * <hot-table [settings]="settings"></hot-table>
 * ```
