Dim dt As Table = Tables("表A")
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

For c As Integer = 0 To dt.Cols.Count -1 '添加列标题
    Sheet(0, c).Value = dt.Cols(c).Name
    If dt.grid.Cols(c+1).Format > "" Then
        Dim Style As Xls.Style = Book.NewStyle '新建一个样式
        Style.Format = dt.grid.Cols(c+1).Format
        sheet.Cols(c).style = style
    End If
Next
For r As Integer = 0 To dt.Rows.Count - 1 '填入数据
    For c As Integer = 0 To dt.Cols.Count -1
        Sheet(r +1, c).Value = dt.rows(r)(c)
    Next
Next
'打开工作簿
Book.Save("c:\reports\test.xls")
Dim Proc As New Process
Proc.File = "c:\reports\test.xls"
Proc.Start()

1、你可以先用saveexcel把表格弄出来；再打开这个xls文件，设置2楼的样式。

2、你可以在2楼的代码基础上，把汇总行也弄出去 http://www.foxtable.com/webhelp/scr/1594.htm
