主题：怎么用数据表，循环数据表中的uuid生成目录页呢？

省略号是直接不能省的  所以难度就在这里

用表格两列  就无法显示这个省略号  显得不美观

看看老师还有没有变通处理的办法呢？

当前代码如下：

''''

Dim cct As Integer = 56 ‘一行显示的字符字节数
Dim doc As New PrintDoc
Dim ss As String
Dim rt As New prt.RenderText
rt.Text = "目录"  & vbcrlf
rt.Style.Font= New Font("方正小标宋简体", 22, FontStyle.Bold)
rt.Style.TextAlignHorz = prt.AlignHorzEnum.Center

doc.Body.Children.Add(rt)
For Each s As String() In DataTables("a").getvalues("文件类别|文件类别名称")
    output.show(CLNum(s(0)) & "、" &  s(1))
    rt = New prt.RenderText
    rt.Text = CLNum(s(0)) & "、" &  s(1)
    rt.Style.Font= New Font("黑体", 16, FontStyle.Bold)
    doc.Body.Children.Add(rt)
    For Each dr As DataRow In DataTables("a").Select("文件类别名称='" & s(1) & "'","文件序号")
        output.show(dr("文件序号")& "." & dr("文件名称")  & "……" & dr("文件编号"))
        rt = New prt.RenderText
        rt.Style.Font= New Font("宋体", 16, FontStyle.Bold)
        rt.Style.LineSpacing=200
        Dim a As String = dr("文件序号")& "." & dr("文件名称")

Dim la As Integer = ukey.LenStrA(a) 
        Dim b As String = dr("文件编号")

Dim lb As Integer = ukey.LenStrA(b) 
        Dim sab As String = a & "".PadLeft((cct - la - lb)/2,"…") &  b

        rt.Text =  sab
        doc.Body.Children.Add(rt)
    Next
Next
doc.Preview()
