PB的datawindow导出到excel文件（支持计算列和显示格式）

//====================================================================

// [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
