--  凑成偶数页打印，并填充空白行

如果总页数是单数，加空白页凑成双数页，并填充空白行，怎么改代码？
Dim doc As New PrintDoc
Dim tb As Table = Tables("订单")
Dim prs As Integer = 20 \'每页20行
For p As Integer = 0 To math.Ceiling(tb.Rows.Count / prs) - 1
    Dim rt As New prt.RenderTable
    rt.Style.Gridlines.All = New prt.Linedef(Color.Gray)
    rt.CellStyle.Spacing.All = 0.5
    For c As Integer = 0 To tb.Cols.Count - 1
        rt.Cells(0,c).Text = tb.Cols(c).Name
    Next
    For r As Integer = p * prs To math.min(tb.Rows.Count - 1,( p + 1) * prs - 1)
        For c As Integer = 0 To tb.Cols.Count - 1
            rt.Cells(r - p * prs + 1, c).Text = tb.rows(r)(c)
        Next
    Next
    If p = math.Ceiling(tb.Rows.Count / prs) - 1 \'如果是最后一页
        For r As Integer = tb.Rows.Count To ( p + 1) * prs - 1 \'补空行
            rt.Rows.Count = rt.Rows.Count + 1
            rt.Rows(rt.Rows.count -1)(0).text = " "
        Next
    Else
        rt.BreakAfter = prt.BreakEnum.Page \'否则换页
    End If
    doc.Body.Children.Add(rt)
Next
doc.Preview()
