主题：转成外部表后，引用就不好用了

AfterOpenProject 这段代码，要删掉

Dim lst As List(Of String)
lst = Connections("jxc").GetTableNames
For Each nm As String In lst
If DataTables.Contains(nm) = False Then '如果表C没有加载
    DataTables.Load(nm) '加载表C
End If
Next

如果是关联表，必须一起加载进来，否则公式会报错 http://www.foxtable.com/webhelp/scr/2755.htm

或者改成

Dim lst As List(Of String)
lst = Connections("jxc").GetTableNames
Dim str As String = String.Join("|", lst.ToArray)
msgbox(str)
DataTables.Load(str)

手动添加外部数据表啊
