标题：请教：如何根据列名称或列内容自动获得最大列宽？

有时列名只有两个字，但是列中内容的字却很多，比如：部门列，有可能会有七八个或是十几个字，而合同结束时间，列名长，而内容却只有八位，那么，如何让系统自动根据情况选择列宽呢？如列名小于内容的宽度，就选内容的宽度，而如果内容小于列名，就选列名的宽度？
主要是用在窗口的表中

MaxLength

如果是字符列，返回该列允许输入的最大长度，否则返回-1。

例如：

Dim Len As Integer
Len = DataTables("订单").DataCols("产品").MaxLength
Output.Show(Len)

如何获得列宽呢？列宽和字符长度如何对应？

Dim Len As Integer
with currenttable
    For Each c As Col In CurrentTable.Cols
        len = datatables(currenttable.name).datacols(c.name).maxlength
        Output.Show(c.Index & "  " & c.name & "    " & len )
    next
end with
这个就是列设置时的允许最大的字符数啊。列宽用Width取得吧。

这样都有了：：：：

Dim Len As Integer
Dim n As Integer
Dim s as string
with currenttable
    For Each c As Col In CurrentTable.Cols
        len = datatables(currenttable.name).datacols(c.name).maxlength
        s = currenttable.Cols(n).Width
        Output.Show(c.Index & "  " & c.name & "    " & len & "  => " & s)  
                    '''   （列序号              列名              列设置的字符长    列宽度)
        n = n + 1
    next
end with

这个更全啦：  如果都是字符型的列：
Dim Len As Integer
Dim n As Integer
Dim n0 As Integer
Dim s as string
with currenttable
    For Each c As Col In CurrentTable.Cols
        len = datatables(currenttable.name).datacols(c.name).maxlength
        s = currenttable.Cols(n).Width
        for i as integer = 0 to currenttable.count -1
            if currenttable.rows(i)(c.name).length > n0
                n0 = currenttable.rows(i)(c.name).length
            end if
        next
        Output.Show("【列位置: 】" & c.Index & " 【列名:】  " & _
        c.name & " 【列设置的字符长度:】  " & len & "  【列宽:】 " & _
        s & " 【本列已输入的最大字符长:】 " & n0)
        n = n + 1
    next
end with

还是无法比较，因为maxlength只对字符型有效
谢谢老师！

我只能是先这样做了：

Dim n,len As Integer
Dim s As Integer
For Each cl As DataCol In DataTables("RS_统计查询_Table2").DataCols
len = datatables("RS_统计查询_Table2").datacols(cl.name).maxlength
s = Tables("RS_统计查询_Table2").Cols(n).PrintWidth
If cl.name.Length < Math.Abs(len)
Tables("RS_统计查询_Table2").Cols(n).PrintWidth = Math.Abs(len)
Else
Tables("RS_统计查询_Table2").Cols(n).PrintWidth = cl.name.Length *5

End If
n = n + 1
Next

这样不管是什么列类型：

Dim Len,n As Integer
Dim s as string
with currenttable
    For Each c As Col In CurrentTable.Cols
            len = datatables(currenttable.name).datacols(c.name).maxlength
            s = currenttable.Cols(n).Width
            Dim s1 as string = 0
            dim nn as string
            for i as integer = 0 to currenttable.count -1
                nn = "" & currenttable.rows(i)(c.name) & ""
                if s1 < nn.length
                    s1 = nn.length
                end if
            next
            Output.Show("【列位置: 】" & c.Index & " 【列名:】  " & _
            c.name & " 【列设置的字符长度:】  " & len & "  【列宽:】 " & _
            s & " 【本列已输入的最大字符长:】 " & s1)            
        n = n + 1
    next
end with

要不用模拟按键试试系统的最佳列宽
