在 vba 数组中导入多文件 dat

Question

我想将多个 dat 文件导入一个带有工作表名称“selectfile”的工作表和一个名为“TableDat”的表。 实际记录是 100000。我快速尝试了下面的代码，但我无法将所有数据文件放入一张表中，因为我希望 output 看起来像下面的 excel 屏幕截图所示。 如果有其他非常快的建议，那么我接受。 我还附上了 dat 文件的屏幕截图。

谢谢罗伊

Sub importmultidat()

Dim myFileNames As Variant
Dim iCtr As Long
myFileNames = Application.GetOpenFilename _
(filefilter:="DAT Files, *.DAT", MultiSelect:=True)

If IsArray(myFileNames) Then
For iCtr = LBound(myFileNames) To UBound(myFileNames)
Workbooks.OpenText Filename:=myFileNames(iCtr), _
Origin:=437, StartRow:=1, DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=True, _
Tab:=True, Semicolon:=False, Comma:=False, Space:=True, _
Other:=False, FieldInfo:=Array(1, 1)
Next iCtr
End If

End Sub
