基于，Microsoft Access 如何知道为索引字段集合创建的字段与 TableDef 字段集合中的等效字段关联？
Even in 此 Microsoft 支持页面 https://support.microsoft.com/en-us/kb/217011，字段是created对于索引，然后附加到索引的字段集合：
...
'Copy Indexes
For I1 = 0 To SourceTableDef.Indexes.Count - 1
Set SI = SourceTableDef.Indexes(I1)
If Not SI.Foreign Then ' Foreign indexes are added by relationships
Set I = T.CreateIndex()
' Copy Jet Properties
On Error Resume Next
For P1 = 0 To I.Properties.Count - 1
I.Properties(P1).Value = SI.Properties(P1).Value
Next P1
On Error GoTo 0
' Copy Fields
For f1 = 0 To SI.Fields.Count - 1
Set F = T.CreateField(SI.Fields(f1).Name, T.Fields(SI.Fields(f1).Name).Type)
I.Fields.Append F
Next f1
T.Indexes.Append I
End If
Next I1
...
我不能简单地添加 TableDef 字段集合中的现有字段吗？这毫无意义，而且似乎缺乏凝聚力。
Update
我实际测试了代码here https://support.microsoft.com/en-us/kb/217011这基本上就是我想做的......但它失败并出现未定义对象错误：
Set F = T.CreateField(SI.Fields(f1).Name, T.Fields(SI.Fields(f1).Name).Type)
...当我们改变这一点时，我们会得到各种各样的乐趣。
（2016 年 5 月 23 日）此外，这个脚本似乎是错误的 - 第二个参数实际上不应该在那里，它是不必要的。省略它会导致进一步的错误！哈！我的尾巴在哪里？我感觉我应该去追它。
我的问题的解决方案
我决定跟随 HansUp 的领导并使用 DDL - 比尝试查找与对象操作相关的问题要容易得多（尽管在最终的代码设计中存在一定程度的问题）...
