主题：条件导出excl

表中，发货列条件满足 为“已发货"和”订单状态为”确定“的订单，则本行的数据就可以导出excl，这个应该怎么加入到下面的公式中？

如何在这个导出代码前面加个条件？

dt.filter = "发货状态='已发货' and 订单状态='确定'"

应该怎么加在里面啊？我加进去，把表格内的全部都筛选掉了···这个代码加在哪里？

比如

 

Dim dt As Table = Tables("订单管理")
dt.filter = "发货状态='已发货' and 订单状态='确定'"
Dim nms() As String = {"订单编号","订单日期","客户名称","细分门型","料型","颜色","门高","门宽","扇数","玻璃高","玻璃宽","玻璃类型","玻璃款式","生产备注"} '要导出的列名
Dim caps() As String = {"订单编号","订单日期","客户名称","细分门型","料型","颜色","门高","门宽","扇数","玻璃高","玻璃宽","玻璃类型","玻璃款式","生产备注"} '对应的列标题
Dim szs() As Integer = {100,100,100,100,100,100,60,60,40,60,60,60,100,100} '对应的列宽
Dim Book As New XLS.Book '定义一个Excel工作簿
Dim Sheet As XLS.Sheet = Book.Sheets(0) '引用工作簿的第一个工作表
Dim st As XLS.Style = Book.NewStyle '日期列的显示格式
st.Format = "yyyy-MM-dd"
For c As Integer = 0 To nms.length -1
    Sheet(0, c).Value = caps(c) '指定列标题
    Sheet.Cols(c).Width = szs(c) '指定列宽
    If dt.Cols(nms(c)).IsDate Then '如果是日期列
        Sheet.Cols(c).Style = st '设置显示格式
    End If
Next
For r As Integer = 0 To dt.Rows.Count - 1 '填入数据
    For c As Integer = 0 To nms.length -1
        Sheet(r +1, c).Value = dt.rows(r)(nms(c))
    Next
Next
Dim dlg As New SaveFileDialog '定义一个新的SaveFileDialog
dlg.Filter= "Excel文件|*.xls" '设置筛选器
If dlg.ShowDialog = DialogResult.Ok Then
    Book.Save(dlg.FileName)
    Dim Proc As New Process
    Proc.File = dlg.FileName
    Proc.Start()
End If
