请问，为什么我没有选择任何一个复选框，预览的时候，还是会固定显示其中的三列，会是在哪里出错？预览代码如下：

Dim tb As Table = Tables("t246")

For Each c As Col In tb.Cols

c.visible = False

Dim lst As WinForm.CheckedListBox

lst = Forms("报表").Controls("CheckedListBox1")

tb.Cols("F4362").visible = lst.GetItemChecked(0)

tb.Cols("F4363").visible = lst.GetItemChecked(1)

tb.Cols("F4366").visible = lst.GetItemChecked(2)

tb.Cols("F4383").visible = lst.GetItemChecked(3)

tb.Cols("F4384").visible = lst.GetItemChecked(4)

tb.Cols("F4385").visible = lst.GetItemChecked(5)

tb.Cols("F4386").visible = lst.GetItemChecked(6)

tb.Cols("F4387").visible = lst.GetItemChecked(7)

tb.Cols("F4388").visible = lst.GetItemChecked(8)

tb.Cols("F4389").visible = lst.GetItemChecked(9)

tb.Cols("F4390").visible = lst.GetItemChecked(10)

tb.Cols("F4391").visible = lst.GetItemChecked(11)

tb.Cols("F4393").visible = lst.GetItemChecked(12)

tb.Cols("F4392").visible = lst.GetItemChecked(13)

tb.Cols("F4397").visible = lst.GetItemChecked(14)

tb.Cols("F4398").visible = lst.GetItemChecked(15)

tb.Cols("F4399").visible = lst.GetItemChecked(16)

tb.Cols("F4407").visible = lst.GetItemChecked(17)

tb.Cols("F4408").visible = lst.GetItemChecked(18)

tb.Cols("F4409").visible = lst.GetItemChecked(19)

tb.Cols("F4410").visible = lst.GetItemChecked(20)

tb.Cols("F5319").visible = lst.GetItemChecked(21)

tb.Cols("F4411").visible = lst.GetItemChecked(22)

tb.Cols("F5296").visible = lst.GetItemChecked(23)

tb.Cols("F4416").visible = lst.GetItemChecked(24)

Dim doc As New PrintDoc '定义一个新报表

Dim rt As New prt.RenderTable '定义一个新表格

Dim hd As Integer = tb.HeaderRows '获得表头的层数

doc.PageSetting.Landscape = True

rt.Style.Font = tb.Font

tb.CreateReportHeader(rt,False) '生成表头,包括所有列

For c As Integer = 0 To tb.Cols.Count -1 '逐列设置和填入内容

rt.Cols(c).Width = tb.Cols(c).PrintWidth '列宽等于实际列宽

If tb.Cols(c).IsNumeric OrElse tb.Cols(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 = 0 To tb.Rows.Count -1 '开始填入该列内容

rt.Cells(r + hd, c).Text = tb(r,c)

rt.Style.Gridlines.All = New prt.Linedef(Color.Gray) '灰色网格线

rt.CellStyle.Spacing.All = 0.5 '单元格内距设为0.5毫米

rt.RowGroups(0, tb.HeaderRows).Header = prt.TableHeaderEnum.All '利用行组功能设置表头

doc.Body.Children.Add(rt) '将表格加入到报表

doc.Preview()

For Each c As Col In tb.Cols

c.visible = True
