请指教，窗口有多列，只显示部分列，在窗口的输出按键设置如下代码，

Dim Book As New XLS.Book(ProjectPath & "Attachments\\订货.xls")
Dim fl As String = ProjectPath & "Reports\\订货单.xls"
Book.Build() \'生成细节区
Book.Save(fl) \'保存工作簿
Dim Proc As New Process \'打开工作簿
Proc.File = fl
Proc.Start()

模板没问题。你窗口表有多少行数据，就会导出多少行的。

但你的模板应该用关联表的方式设计 http://www.foxtable.com/webhelp/scr/0204.htm

如果还有问题，做个例子上来看看。

\'将窗口明细表直接打印,已测试可用,勿删!!!
\'Dim Book As New XLS.Book(ProjectPath & "Attachments\\订货.xls")
\'Dim fl As String = ProjectPath & "Reports\\订货单.xls"
\'Book.Build() \'生成细节区
\'Book.Save(fl) \'保存工作簿
\'Dim Proc As New Process \'打开工作簿
\'Proc.File = fl
\'Proc.Verb = "Print" \'指定动作
\'Proc.Start()

\'将窗口明细表的列导出EXCEL表,保存在c:\\reports\\工程需求.xls,已测试可用,勿删!!!
Dim Book As New XLS.Book(ProjectPath & "Attachments\\订货.xls") \'模板存放位置
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Sheet(5,6).Value = "制单人:" & User.Name \'修改模板,加入制单人信息
Dim fl As String = ProjectPath & "Reports\\订货单.xls" \'导出后excel表存放位置
Book.Build() \'生成细节区
Book.Save(fl) \'保存工作簿
Dim Proc As New Process \'打开工作簿
Proc.File = fl
Proc.Start()
