 * A `` is used to make groups of columns in `` and
 * to configure additional headers and footers.
 *
 * Groups can be nested to create complex header and footer configurations.
 *
 * #### Example:
 * ```html
 * 
 *   
 *   
 * 
 * ```
 *
 * ```js
 * const columnGroup = document.querySelector('#columnGroup');
 * columnGroup.headerRenderer = (root, columnGroup) => {
 *   root.textContent = 'header';
 * }
 *
 * const column1 = document.querySelector('#column1');
 * column1.headerRenderer = (root, column) => { ... };
 * column1.renderer = (root, column, model) => { ... };
 *
 * const column2 = document.querySelector('#column2');
 * column2.headerRenderer = (root, column) => { ... };
 * column2.renderer = (root, column, model) => { ... };
