试试这个(为 Excel 2007+ 编写,可能不适用于早期版本)
Private Sub CommandButton1_Click()
    Dim book As Workbook
    Dim lst As ListObject
    Dim iList As Worksheet
    Dim Rng As Range
    Dim wbAllDataBook As Workbook
    Dim shAllData As Worksheet
    ' Get reference to ALLDATA table
    Set wbAllDataBook = Workbooks("ALLDATABOOK.xlsm")  '<-- change to suit your file extension
    Set shAllData = wbAllDataBook.Worksheets("ALLDATA")
    Set lst = shAllData.ListObjects("Table1")
    For Each book In Workbooks
        ' Use error handler to avoid looping through all worksheets
        On Error Resume Next
        Set iList = book.Worksheets("Test")
        If Err.Number <> 0 Then
            ' sheet not present in book
            Err.Clear
            On Error GoTo 0
        Else
            ' If no error, iList references sheet "Test"
            On Error GoTo 0
            ' Get Reference to named range
            Set Rng = iList.[Table]
            ' Add data to row below existing data in table.  Table will auto extend
            If lst.DataBodyRange Is Nothing Then
                ' Table is empty
                lst.InsertRowRange.Resize(Rng.Rows.Count).Value = Rng.Value
            Else
                With lst.DataBodyRange
                    .Rows(.Rows.Count).Offset(1, 0).Resize(Rng.Rows.Count).Value = Rng.Value
                End With
            End If
        End If
    Next
End Sub
更新:
要与 Excel 2003 一起使用,请替换
If lst.DataBodyRange Is Nothing Then
和
If Not lst.InsertRowRange Is Nothing Then
