只关注listeners就行，完全可行

var　e　＝　MainGrid．getSelectionModel（）．selection．record；e．set（＆＃39；depid＆＃39；，　＆＃39；10000＆＃39；）；e．set（＆＃39；depname＆＃39；，　＆＃39；总部＆＃39；）；var　depid　＝　e．get（＆＃39；depid＆＃39；）；var　depname　＝　e．get（＆＃39；depname＆＃39；）；这个record其实就是一个json对象

首先导入扩展CheckColumn的JS文件在extjs文件包的/examples/ux/CheckColumnjs。 然后将你要用来显示true/false的那列的xtype配置成checkcolumn。 例子: {xtype:"checkcolumn",header:"头部",dataIndex:"xxxx"}

单击某个单元格时，选中的是整行，Ext默认的是RowSelectionModel——行选择模型。

行选择模型默认支持多选，鼠标单击时按住ctrl/shift就可以选择多行。如果只希望选择一行，设置singleSelect参数为true。 在Grid中设置sm为RowSelectionModel，并指
