Несмотря на то, что ExtJs GridPanel имеет богатый контроль данных, он имеет ограниченную функциональность замораживания столбцов.
Только первый столбец может быть заблокирован с помощью заблокированного атрибута.
Кто-нибудь решил эту проблему?
Вот мой код:
Ext.require(['Ext.grid.*', 'Ext.data.*', 'Ext.util.*', 'Ext.state.*']);
Ext.onReady(function () {
// sample static data for the store
