 * @plugin BindRowsWithHeaders

 * @description
 * Plugin allows binding the table rows with their headers.
 *
 * If the plugin is enabled, the table row headers will "stick" to the rows, when they are hidden/moved. Basically, if
 * at the initialization row 0 has a header titled "A", it will have it no matter what you do with the table.
 *
 * @example
 * ```js
 * const container = document.getElementById('example');
 * const hot = new Handsontable(container, {
 *   data: getData(),
 *   // enable plugin
 *   bindRowsWithHeaders: true
 * });
