将XCEL文件按某例拆分文件，并保留两行表头。如何保持原表的列宽、行高不变？

将XCEL文件按某例拆分文件，并保留两行表头。如何保持原表的列宽、行高不变？
原代码和附件如下，请教，如何修改？



Sub 保留2行表头拆分数据为若干新文件()
    Dim arr, d As Object, k, t, i&, lc%, rng As Range, c%
    c = Application.InputBox("请输入拆分列号", , 1, , , , , 1)
    If c = 0 Then Exit Sub
    Application.ScreenUpdating = False
    Application.DisplayAlerts = False
    arr = [a1].CurrentRegion
    lc = UBound(arr, 2)
    Set rng = [a1].Resize(2, lc)   '保留2行表头
    Set d = CreateObject("scripting.dictionary")
    For i = 3 To UBound(arr)    '从第3行往下复制
        If Not d.Exists(arr(i, c)) Then
            Set d(arr(i, c)) = Cells(i, 1).Resize(1, lc)
        Else
            Set d(arr(i, c)) = Union(d(arr(i, c)), Cells(i, 1).Resize(1, lc))
        End If
    Next
    k = d.Keys
    t = d.Items
    For i = 0 To d.Count - 1
        With Workbooks.Add(xlWBATWorksheet)
            rng.Copy .Sheets(1).[a1]
            t(i).Copy .Sheets(1).[a3] '正文从A3往下粘贴
            .SaveAs Filename:=ThisWorkbook.Path & "\" & k(i) & ".xls"
            .Close
        End With
    Next
    Application.DisplayAlerts = True
    Application.ScreenUpdating = True
    MsgBox "完毕"
End Sub
