如何通过VB合并Excel单元格以及设置Excel行高？

例如：我想把第一列的第4，5，6，7行合并。。。我在怎样让合并单元格里的字居中，怎样改变字体。 请不吝赐教。。。

==========================================================

首先在VB中引用microsoft excel object library假设c盘根目录下有个1.xls的文件
…………问题补充：你的要求很简单，一行指令恐怕不行，最少要三行代码如下：Private Sub Form_Load()Dim xlApp As Excel.ApplicationDim xlBook As Excel.WorkbookDim xlSheet As Excel.WorksheetDim i As IntegerSet xlApp = CreateObject("Excel.Application")Set xlBook = xlApp.Workbooks.Open("C:\1.xls")Set xlSheet = xlBook.Worksheets(1) '引用第1张工作表For i = 3 To 100 Step 3 '想到哪行就把100改成几xlSheet.Range(Cells(i, 1), Cells(i, 2)).Merge '合并a1:b2单元格NextxlSheet.Rows(10).RowHeight = 100 '把第10行高度设为100xlBook.SavexlApp.Application.QuitSet xlApp = Nothing '表忘释放引用End Sub运行一下，看看满足要求否。

===========================================================================================

Sub Macro1()Range("A4:A7").Select
With Selection
.HorizontalAlignment = xlCenter
.VerticalAlignment = xlCenter
.WrapText = False
.Orientation = 0
.AddIndent = False
.IndentLevel = 0
.ShrinkToFit = False
.ReadingOrder = xlContext
.MergeCells = False
End With
Selection.Merge
With Selection.Font
.Name = "隶书"
.FontStyle = "常规"
.Size = 12
.Strikethrough = False
.Superscript = False
.Subscript = False
.OutlineFont = False
.Shadow = False
.Underline = xlUnderlineStyleNone
.ColorIndex = xlAutomatic
End With
End Sub
