Dim i As Integer Dim isBlank As Boolean '循环A2-A10单元格 For i=2To10'存储单元格是否为空的结果 isBlank=Cells(i,1).Value=""'如果为空,则用上方的单元格的值填充当前单元格 If isBlank ThenCells(i,1)=Cells(i-1,1)End If Next i End Sub 以上代码运行后,在 A2:A10 单元格区域,依次判断每...

Dim arr As Variant, arrTransposed As Variant arr = Range("A1:B3").Value arrTransposed = Application.WorksheetFunction.Transpose(arr) 5. 执行效率对比 数组操作在处理大量数据时速度显著优于逐行逐列的操作。以下我们通过一个简单的示例对比数组方法与常规方法的执行时间。 假设A列有1万个随机数,要求筛选出...

("Scripting.Dictionary") Dim i As Long For i = 2 To lastRow ' 假设第一行为标题行 dict(ws.Cells(i, 1).Value) = 1 Next i ' 将字典的键值填充到下拉列表框 Dim key As Variant With UserForm1.ComboBox1 .Clear For Each key In dict.Keys .AddItem key Next key End With UserForm1.Show...
With Range("A1").Value = "Hello".Font.Bold = True .Font.Name = "Arial"End With ```在该代码中，with语句指定了Range("A1")作为对象，并在with语句中对其进行了多次操作，比单独指定对象多次使用简单易懂。- 操作同一对象的不同方法：```VBA With Sheets("Sheet1").Range("A1:A10")....
