/**
 * @plugin CollapsibleColumns
 *
 * @description
 * The {@link CollapsibleColumns} plugin allows collapsing of columns, covered by a header with the `colspan` property defined.
 *
 * Clicking the "collapse/expand" button collapses (or expands) all "child" headers except the first one.
 *
 * Setting the {@link Options#collapsibleColumns} property to `true` will display a "collapse/expand" button in every header
 * with a defined `colspan` property.
 *
 * To limit this functionality to a smaller group of headers, define the `collapsibleColumns` property as an array
 * of objects, as in the example below.
 *
 * @example
 * ```js
 * const container = document.getElementById('example');
 * const hot = new Handsontable(container, {
 *   data: generateDataObj(),
 *   colHeaders: true,
 *   rowHeaders: true,
 *   nestedHeaders: true,
 *   // enable plugin
 *   collapsibleColumns: true,
 * });
 *
 * // or
 * const hot = new Handsontable(container, {
 *   data: generateDataObj(),
 *   colHeaders: true,
 *   rowHeaders: true,
 *   nestedHeaders: true,
 *   // enable and configure which columns can be collapsed
 *   collapsibleColumns: [
 *     {row: -4, col: 1, collapsible: true},
 *     {row: -3, col: 5, collapsible: true}
 *   ],
 * });
 * ```
