老师好，下面代码报错。

此主题相关图片如下：图像 1.png

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"} \'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} \'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

dt.filter = "发货状态=true and 订单状态=true"

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！

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 Sheet As XLS.Sheet = Book.Sheets(0) \'引用工作簿的第一个工作表

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
