PB中数据窗口导出数据到EXCEL的程序（2）

//====================================================================
// [PUBLIC] Function uf_data2excel 在 u_data2word inherited from nonvisualobject
//--------------------------------------------------------------------
// 说明:将数据倒入excel中,支持计算列及显示格式,要求在题头的计算列要写tag值
//--------------------------------------------------------------------
// 参数1:[value] datawindow adw
//  说明:数据窗口
//--------------------------------------------------------------------
// 返回: (INTEGER) 成功返回1,不成功返回0
//--------------------------------------------------------------------
//====================================================================
//变更日志：020515加入对交叉表倒出的支持(主要是修改了保存题头部分)
