每张表中[A1：I1]是合并单元格区域，运行提示无法对合并单元格执行操作，
小白，求指导，最好能给出注释。。

Sub combine()
Dim u As Long, t As Long
u = 7
t = 9

Range(Cells(u + 1, 1), Cells(65536, 9)).ClearContents
Application.ScreenUpdating = False
Dim fm As String, wb As Workbook, er As Long, fn As String, arr As Variant, sht As Worksheet
fm = Dir(ThisWorkbook.Path & "\*.xls")
Do While fm <> ""
If fm <> ThisWorkbook.Name Then
er = Range("A1").CurrentRegion.Rows.Count + 1
fn = ThisWorkbook.Path & "\" & fm
Set wb = GetObject(fn)
Set sht = wb.Worksheets(1)
    arr = Range(sht.Cells(u, "A"), sht.Cells(65536, "B").End(xlUp).Offset(0, 9))
    Cells(er, "A").Resize(UBound(arr, 1), UBound(arr, 2)) = arr
    wb.Close savechanges:=False
    End If
    fm = Dir
