 谢谢老师

 老师，我想在原来设置代码的基础上增加功能，把数据导出到工作簿上然后根据客户的名称分散到工作表中。谢谢老师！
Dim dt As Table = Tables("订单管理")
dt.filter = "发货状态=true and 订单状态=true"
Dim nms() As String = {"订单编号","订单日期","客户名称"} '要导出的列名
Dim caps() As String = {"订单编号","订单日期","客户名称"} '对应的列标题
Dim szs() As Integer = {100,100,100,100} '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

 老师，楼上代码能改成多层表头导出。

老师休息时间也打捞你，下面代码有点搞不懂，想修改成指定的保存地址。

 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
    Dim dt As DataTable = DataTables("订单管理")
    Dim nms() As String = {"订单_编号","订单_日期","客户名称"} '要导出的列名
    Dim caps() As String = {"订单_编号","订单_日期","客户名称"} '对应的列标题
Dim hlvl As Integer = 3
    Dim szs() As Integer = {100,100,100,100} '对应的列宽
    Dim Book As New XLS.Book '定义一个Excel工作簿
    For Each mc As String In dt.GetValues("客户名称", "发货状态=true and 订单状态=true and 客户名称 is not null")
        Dim Sheet As XLS.Sheet = Book.Sheets.Add '引用工作簿的第一个工作表
        sheet.name = mc
        Dim drs = dt.Select("客户名称='" & mc & "' and 发货状态=true and 订单状态=true")
        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.dataCols(nms(c)).IsDate Then '如果是日期列
                Sheet.Cols(c).Style = st '设置显示格式
            End If
        Next
