你可以使用Win32 API函数来在指定的Access数据表中创建子表并重命名子表。以下是可以用于创建子表并重命名子表的VBA代码:
```
Option Compare Database
Option Explicit
' Declare Win32 API functions
Private Declare Function CreateTable Lib "dao360.dll" (ByVal db As Long, ByVal Name As String, Optional ByVal Attributes As Long = 0&) As Long
Private Declare Function CreateField Lib "dao360.dll" (ByVal TableDef As Long, ByVal Name As String, ByVal Type As Integer, Optional ByVal Size As Long = 0&, Optional ByVal Attributes As Long = 0&) As Long
Private Declare Function CreateIndex Lib "dao360.dll" (ByVal TableDef As Long, ByVal Name As String, Optional ByVal PrimaryKey As Boolean = False, Optional ByVal Unique As Boolean = False, Optional ByVal Clustered As Boolean = False) As Long
Private Declare Function Append Lib "dao360.dll" (ByVal TableDefs As Long, ByVal Object As Long) As Long
Private Declare Function Rename Lib "dao360.dll" (ByVal TableDef As Long, ByVal Name As String) As Long
Public Sub CreateSubTable()
Dim db As DAO.Database
Dim tdf As DAO.TableDef
Dim fld As DAO.Field
Dim idx As DAO.Index
Dim rel As DAO.Relation
Dim strTableName As String
Dim strFieldName As String
' Set table and field names
strTableName = "MainTable"
strFieldName = "SubTableID"
' Open database
Set db = CurrentDb
' Create subtable
Set tdf = db.CreateTableDef(strTableName & "_" & strFieldName)
CreateTable db.hDb, tdf.Name
' Add fields to subtable
Set fld = tdf.CreateField(strFieldName, dbLong)
CreateField tdf.hTableDef, fld.Name, fld.Type, fld.Size, fld.Attributes
tdf.Fields.Append fld
' Add index to subtable
Set idx = tdf.CreateIndex("PrimaryKey")
idx.Primary = True
idx.Fields.Append fld
CreateIndex tdf.hTableDef, idx.Name, idx.Primary, idx.Unique, idx.Clustered
tdf.Indexes.Append idx
' Append subtable to database
Append db.TableDefs.hTableDefs, tdf.hTableDef
' Create relationship between main table and subtable
Set rel = db.CreateRelation("MainTable_SubTable", strTableName, strTableName & "_" & strFieldName)
rel.Fields.Append rel.CreateField(strFieldName)
rel.ForeignTable = strTableName
rel.Attributes = dbRelationDeleteCascade
db.Relations.Append rel
' Rename subtable
Rename tdf.hTableDef, "NewSubTableName"
End Sub
```
这段代码会在名为"MainTable"的数据表中创建一个名为"MainTable_SubTableID"的子表,包含一个名为"SubTableID"的字段,并且将子表重命名为"NewSubTableName"。请根据自己的需要修改表名和字段名。
