VBA实现相同行合并

帮人捣鼓了个VBA代码用来实现多行合并，具体需求为：列2/列3/列4 相同的情况下，则对应的行合并为一行，且列1用空格隔开，列5则相加；

（对大多数办公室职员，VBA还算是提高效率的一个利器吧）

最终效果如下：

 1 Sub test()
 2   Dim r%, i%
 3   Dim arr, brr
 4   Dim d As Object
 5   Set d = CreateObject("scripting.dictionary")
 6   With Worksheets("sheet1")
 7     r = .Range("a1").End(xlDown).Row
 8     arr = .Range("a2:e" & r)
 9     For i = 1 To UBound(arr)
10       If Not d.exists(arr(i, 2) & arr(i, 3) & arr(i, 4)) Then
11         ReDim brr(1 To UBound(arr, 2))
12         For j = 1 To UBound(arr, 2)
13           brr(j) = arr(i, j)
14         Next
15       Else
16         brr = d(arr(i, 2) & arr(i, 3) & arr(i, 4))
17         brr(1) = brr(1) & " " & arr(i, 1)
18         brr(5) = brr(5) + arr(i, 5)
19 
20       End If
21       d(arr(i, 2) & arr(i, 3) & arr(i, 4)) = brr
22     Next
23     .Range("h2").Resize(d.Count, UBound(brr)) = Application.Transpose(Application.Transpose(d.items))
24   End With
25 End Sub

代码以字典作为实现功能，把列2、列3、列4合并起来作为Key值，列1、列5为Value值，列1则用空格合并，列5则相加。
