一专业报表，要求银行余额为两位小数，如何修改按钮代码，请各位老师指教，谢谢！！

按钮代码如下：

Dim doc As New PrintDoc \'定义一个新报表
Dim tb As Table = Tables("余额明细")  \'捆绑表
Dim ColNames As New List(Of String)
Dim prs As Integer = 30   \'每页30行
Dim sum2 As Double = 0  \'定义双精度变量(小计)
Dim tsum2 As Double = 0 \'定义双精度变量(总计)
For p As Integer = 0 To math.Ceiling(tb.Rows.Count / prs) - 1  \'大循环,计算共几页
    Dim rt As New prt.RenderTable   \'定义一个新表格
    For Each cl As Col In tb.Cols   \'排除隐藏列
        If cl.Visible Then
            ColNames.Add(cl.Name)
        End If
    Next
    rt.Width = "Parent.Width" \'表格宽度等于容器宽度
    rt.CanSplitHorz = True  \'表格宽度超出页宽时,可以水平换页
    rt.Style.Font = tb.Font
    rt.Style.Gridlines.All = New prt.Linedef(Color.Gray)  \'灰色网格线
    rt.CellStyle.Spacing.All = 1.0   \'单元格内距设为1.0毫米
    For c As Integer = 0 To tb.Cols.Count - 1  \'逐列设置和填入内容
        rt.Cells(0,c).Text = tb.Cols(c).Name  \'列名作为标题
        rt.Cells(0,c).Style.TextAlignHorz = prt.AlignHorzEnum.Center   \'标题内容水平居中
        rt.Cols(c).Width = tb.Cols(ColNames(c)).PrintWidth  \'列宽等于实际列宽
        If tb.Cols(ColNames(c)).IsNumeric OrElse tb.Cols(ColNames(c)).IsDate Then \'如果是数值或日期列
            rt.Cols(c).Style.TextAlignHorz = prt.AlignHorzEnum.Right \'数据水平靠右
        End If
        For r As Integer = p * prs To math.min(tb.Rows.Count - 1,( p + 1) * prs - 1)  \'小循环
            rt.Cells(r - p * prs + 1, c).Text = tb.rows(r)(c)
        Next
    Next
    sum2 = 0
    For r As Integer = p * prs To math.min(tb.Rows.Count - 1,( p + 1) * prs - 1) \'累计小计
        sum2 =sum2 + tb.rows(r)("银行余额")
    Next
    tsum2 = tsum2 + sum2
    rt.Rows.Count = rt.Rows.Count + 1 \'增加小计行
    rt.Rows(rt.Rows.count -1)(0).text = "本页小计"
    rt.Rows(rt.Rows.count -1)(2).text = sum2
    If p < math.Ceiling(tb.Rows.Count / prs) - 1
        rt.BreakAfter = prt.BreakEnum.Page
    Else
        rt.Rows.Count = rt.Rows.Count + 1 \'增加总计行
        rt.Rows(rt.Rows.count -1)(0).text = "总计"
        rt.Rows(rt.Rows.count -1)(2).text = tsum2
    End If
    doc.Body.Children.Add(rt)  \'将表格加入到报表
Next
\'设置页眉
Dim rx As New prt.RenderTable
rx.Cells(0,0).Text = Date.Today
rx.Cells(0,1).Text = "银行对账单"
rx.Cells(0,2).Text = "第[PageNo]页,共[PageCount]页"
rx.Cols(0).Style.TextAlignHorz = prt.AlignHorzEnum.Left \'水平靠左
rx.Cols(0).Style.TextAlignVert = prt.AlignVertEnum.Bottom \'垂直靠下
rx.Cols(1).Style.TextAlignHorz = prt.AlignHorzEnum.Center \'水平居中
rx.Cols(2).Style.TextAlignHorz = prt.AlignHorzEnum.right \'水平靠右
rx.Cols(2).Style.TextAlignVert = prt.AlignVertEnum.Bottom \'垂直靠下
rx.Style.Borders.Bottom = New prt.LineDef \'设置底边框
rx.CellStyle.Spacing.Bottom = 1 \'底端内容缩进1.0毫米
rx.Cells(0,1).Style.FontSize = 14  \'设置第二列行字号
rx.Cells(0,1).Style.FontBold = True \'字体加粗
Doc.PageHeader = rx \'作为页眉使用
Doc.Preview() \'预览

谢谢程老师的回复，这次的问题与上次有点区别，但是参照上次的解决方案，已解决了金额列的数字格式化问题.

但是还存在小计、总计值的格式化没有解决，还望指教，谢谢！！

解决金额列格式化的代码如下：

        For r As Integer = p * prs To math.min(tb.Rows.Count - 1,( p + 1) * prs - 1)  \'小循环
            rt.Cells(r - p * prs + 1, c).Text = tb.Rows(r)(c)
            If (ColNames(c)) = "银行余额" \'设置格式
                rt.Cells(r - p * prs + 1, c).Text = format(tb.Rows(r)(ColNames(c)),"00.00")
            Else
                rt.Cells(r - p * prs + 1, c).Text = tb.Rows(r)(c)
            End If
        Next

去掉.text：

 rt.Rows(rt.Rows.count -1)(2) = format(sum2,"0.00")
 rt.Rows(rt.Rows.count -1)(2) = format(tsum2,"0.00")

和上次要解决的没啥两样！

谢谢程老师的回复，但是出现错误提示，请指教，谢谢！！
