 ###最近三次更新:

+#### 更新2017/01/11
+* 增加AnyCol来对应FilterCol方法，只保留AnyCol类列
+* 增加SetCellStyle，突破CellStye绑定wk约束，链式设置列单元格风格（非常狗血）

 #### 更新2017/01/09
 * 增加SetPath方法，随时切换保存路径
 * 增加ConvertName方法，方便自定义Excel列名称

 #### 更新2017/01/06
 * 整合注解，导出和读取使用同一个ExcelAnno注解
 * 统一编码为UTF-8

-#### 更新2017/01/05
 * 修复据库查询的导出(Object)递归越栈问题
 * 增加新的xxx.Class定义类型导出，操作更简单
 * 导出注解支持(自己使用seven.savewapper.anno.ExcelAnno类型注解)
