VBA可以实现一个文件夹内所有表格合并在一个数组里嘛？

是的，VBA（Visual Basic for Applications）可以实现这个功能。你可以编写一段代码来遍历指定文件夹内的所有Excel工作簿或表格，并将它们的内容添加到一个数组或者数据结构中。以下是一个简单的步骤概述：

1. 使用`Folder.Files`属性获取文件夹中的所有文件路径。
2. 遍历每个文件，判断是否为Excel (.xls, .xlsx) 文件。
3. 对于每个Excel文件，使用`Application.Workbooks.Open`打开它，然后读取工作表的数据。
4. 将工作表数据存储在一个二维数组或其他适合的地方。
5. 关闭已打开的工作簿。

下面是一个简化的示例代码片段，但这需要进一步修改和完善，例如错误处理和优化性能：

Sub MergeSheetsIntoArray()
    Dim folderPath As String
    Dim excelApp As Object
    Dim workbook As Object
    Dim sheet As Worksheet
    Dim dataArray() As Variant
    Dim filePath As String
    
    ' Set the folder path here
    folderPath = "C:\Your\Folder\Path"
    
    ' Initialize the array to store data
    ReDim dataArray(1 To 1, 1 To 1)
    
    Set excelApp = CreateObject("Excel.Application")
    excelApp.Visible = False ' Make Excel run in background
    
    For Each filePath In GetFiles(folderPath, "*.xls*") ' Modify this line with your file filter
        If Right(filePath, 4) = ".xlsx" Then
            Set workbook = excelApp.Workbooks.Open(filePath)
            
            For Each sheet In workbook.Sheets
                ' Read and append sheet data (replace 'A1' with appropriate range)
                dataArray(UBound(dataArray, 1), UBound(dataArray, 2)) = sheet.Range("A1").Value
                ' Adjust the dimensions as needed
                ReDim Preserve dataArray(1 To UBound(dataArray, 1) + 1, 1 To UBound(dataArray, 2))
            Next sheet
            
            workbook.Close SaveChanges:=False ' Close the workbook without saving
        End If
    Next filePath
    
    ' Process or save the combined data as needed
    ' ...

End Sub

Private Function GetFiles(ByVal rootDir As String, ByVal extFilter As String) As Collection ' Returns a Collection of files matching the extension
    Dim collection As New Collection
    Dim fso As Object
    Set fso = CreateObject("Scripting.FileSystemObject")
    
    Dim subfolders() As String
    subfolders = fso.GetFolder(rootDir).SubFolders
    Dim subdir As String
    
    For Each subdir In subfolders
        collection.AddJoin "Path", subdir.Path & "\" & extFilter, collection, "Path", rootDir & "\" & extFilter
        collection.AddRange fso.GetFiles(subdir.Path, extFilter)
    Next subdir
    
    Set collection = Nothing
    Set fso = Nothing
    Exit Function
Next Function
