Excel·VBA指定目标值切割分组

看到一个帖子《excel吧-数据切断分组问题》，对1列数据按指定长度进行切割分组，获取每组的长度组成方式

• VBA代码

Sub 数据分割()
    Dim arr, target, brr, res, x&, y&, i&, 差额, trr(1 To 2)  'trr(0)为数值，trr(1)为组成方式
    arr = [a1].CurrentRegion: target = 10: deg = 2  '待分割数据，目标值，计算精度
    brr = Array(): x = -1: res = Array(): y = -1
    For Each a In arr  '多行多列的，按列从左往右读取
        x = x + 1: ReDim Preserve brr(x): brr(x) = a
    Next
    Do
        If trr(1) + brr(i) >= target Then
            差额 = target - trr(1): trr(2) = trr(2) & "+" & CStr(差额)
            y = y + 1: ReDim Preserve res(y): res(y) = Mid(trr(2), 2)  '去除开头的+
            trr(1) = 0: trr(2) = "": brr(i) = Round(brr(i) - 差额, deg)  '更新数组
        Else
            trr(1) = trr(1) + brr(i): trr(2) = trr(2) & "+" & CStr(brr(i))
            i = i + 1  '下一个
        End If
        If i < x Then  '避免结果开头为0+
            If brr(i) = 0 Then i = i + 1  '下一个
        End If
        If i = x Then  '剩余部分
            If brr(i) < target Then y = y + 1: ReDim Preserve res(y): res(y) = brr(i)
        End If
    Loop Until i > x
    [d1].Resize(UBound(res) + 1, 1) = WorksheetFunction.Transpose(res)
End Sub
