重新配置ExtJs4中的网格列 - SelModel消失？

问题描述

我正在定义一个具有 selModel 的网格。

每次加载商店时，网格列都会使用网格方法。 >
但是当我这样做时，网格 selModel 消失。

我如何重新配置​​网格列也包含selModel。 >
以下是一些示例代码：

I am defining a grid which has a selModel.
Each time the store loads, the grids columns are dynamically reconfigured using the grids Reconfigure method.
However when I do this the grids selModel disappears.
How can I reconfigure the grids columns to also include the selModel.
Below is some example code:

//The Selection Model for the grid.
var sm = new Ext.selection.CheckboxModel();

//The Grid
var grid = new Ext.grid.Panel({
    store: store,
    selModel: sm,
    columns:[{
            header: 'Loading ...'
        }]
 });

//The store on load event where the columns are reconfigured
store.on('load', function(store){
    var columns = store.data.Data.items;
    grid.reconfigure(store, columns);
}, this);

在ExtJs3中，我可以将selModel指定为列本身，但ExtJs4不是这样。那么如何确保selModel即使在重新配置网格列之后总是可见？

In ExtJs3 I could specify the selModel as a column itself but this is not the case in ExtJs4. So how can I ensure the selModel is always visible even after reconfiguring the grids columns?
