extjs

(类的叫法可能不准确，但extjs就是这么写的)

Class Ext.grid.Column类的属性renderer对应函数参数说明可以参考ColumnModel.setRenderer( Number col, Function fn )

setRenderer需要设置行号，参数说明也在此，record参数就是Ext.data.record

Ext.data.record说明

data : Object

An object hash representing the data for this Record. Every field name in the Record definition is represented by a property of that name in this object. Note that unless you specified a field with name "id" in the Record definition, this will not contain an id property.

除了名为id的属性可以直接获取，其他属性都需要通过data获取

也可以直接record.get(属性名)获取；

感觉和jquery的grid相关插件很相似，似乎所有的js表格组件如属性等都很相似。
