combobox Grid 多列

未完善版，后期将贴出完善版，完善版主要是封装了grid

* 部分特定配置方法如下（其他的和ComboBox一样）：

* ------------------------------------------

* 如果需要对grid有特殊的配置，请使用 gridCfg 配置项

* url: [必须] 数据源url

* columns：[必须] grid的cm

* displayField : [必须] 显示对应的列默认为 text

* valueField : [必须] 值对应的列默认为 value

* paging： [可选] 是否分页默认false不分页

* fields： [可选] store的数据列、默认是根据columns的dataIndex构造出了的

* ------------------------------------------
