Dim Sheet As XLS.Sheet = Book.Sheets(0)
tbl.CreateSheetHeader(Sheet,0,0,False) '生成表头
For c As Integer = 0 To tbl.Cols.Count - 1
    For r As Integer = 0 to tbl.Rows.Count - 1
        sheet(r + hdr,c).value = tbl(r,c)
    Next

Book.Save("c:\reports\test.xls")
Dim Proc As New Process
Proc.File = "c:\reports\test.xls"
Proc.Start()
