如下，是我导出的代码：

Dim dt As Table = Tables("峰和设计部_table1")

Dim nms() As String = {"接单日期","量房时间","市场部","设计师","操作性","客户姓名","联系电话","小区地址","楼号","区域","面积","平面定金","立面定金金额","预收设计费","当月预签","预签时间","户型","设计部客户操作备注"} '要导出的列名

Dim caps() As String = {"接单日期","量房时间","市场部","设计师","操作性","客户姓名","联系电话","小区地址","楼号","区域","面积","平面定金","立面定金金额","预收设计费","当月预签","预签时间","户型","设计部客户操作备注"} '对应的列标题

Dim szs() As Integer = {90,90,70,70,70,80,100,90,80,70,50,80,80,85,80,90,40,120} '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

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))

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
