Nested Grids in rowbody ExtJS 4 (Вложенные гриды в rowbody в ExtJS 4)

[betazold]

The main idea is have some div where nested grid will be rendered

   Ext4.define('Company', {
        extend: 'Ext4.data.Model',
        fields: [
            {name: 'id', type: 'int' },
            {name: 'company', type: 'string'},
            {name: 'price', type: 'float'},
            {name: 'change', type: 'float'},
            {name: 'pctChange', type: 'float'},
            {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'},
            {name: 'industry'},
            {name: 'desc'}
         ]
    });
 
    // Array data for the grids
