Question

我试图在数据集中对由列分隔的列内的值求和。循环似乎正在迭代，但是在即时窗口内输出的循环“a”中的值不是我预期的;它似乎引用了A列中的1个单元格，5x。该脚本包含描述我正在尝试实现的内容的注释。

Sub sumCells()

Dim i, r, a, numObs As Integer
Dim Fa, Fb, Fc, Fd, Fe As Long

numObs = 10

Dim subStart As Integer

'loop to separate data into "blocks" of 10 rows (numObs). Step function used
'to contain loops below within each block. starts at 2 due to headers
For subStart = 2 To sheet1.UsedRange.Rows.Count Step numObs

   'loop to reference the rows within the subStart loop block
    For r = 2 To numObs

      'Loop to reference columns 1 through 5 (ideally I'd like to be able to
       'have this reference the actual column index so i dont have to
       'include more lines above to arrange the data accordingly
        For a = 1 To 5

           'this section is supposed to sum the values within each column
           'in this case, columns 1 to 5, within the rows specified above
           Fa = WorksheetFunction.Sum(Cells(r, 1))
           Fb = WorksheetFunction.Sum(Cells(r, 2))
           Fc = WorksheetFunction.Sum(Cells(r, 3))
           Fd = WorksheetFunction.Sum(Cells(r, 4))
           Fe = WorksheetFunction.Sum(Cells(r, 5))

       Next a

  Next r

Next subStart

End Sub

数据样本，数据从第2行开始，不包括标题：

假设您想要在每列中对每个十个块进行求和并将其打印到即时窗口，则此代码应该有效：

Sub sumcols()

Dim blocks As Integer
Dim Fa As Long, Fb As Long, Fc As Long, Fd As Long, Fe As Long
Dim i As Long, j As Long

blocks = 9

For i = 2 To Sheets("sheet1").Range("A1048576").End(xlUp).Row Step blocks + 1 'A1048576' will need to be changed if excel version older than '07
    'get sums for columns a through e for block starting with row i

    Fa = Application.WorksheetFunction.Sum(Sheets("sheet1").Range("A" & i & ":A" & i + blocks))
    Fb = Application.WorksheetFunction.Sum(Sheets("sheet1").Range("B" & i & ":B" & i + blocks))
    Fc = Application.WorksheetFunction.Sum(Sheets("sheet1").Range("C" & i & ":C" & i + blocks))
    Fd = Application.WorksheetFunction.Sum(Sheets("sheet1").Range("D" & i & ":D" & i + blocks))
    Fe = Application.WorksheetFunction.Sum(Sheets("sheet1").Range("E" & i & ":E" & i + blocks))

    'print values to immediate window
    Debug.Print Fa
    Debug.Print Fb
    Debug.Print Fc
    Debug.Print Fd
    Debug.Print Fe

Next i

End Sub

编辑：

使列迭代也使用：

（在这种情况下，Fa将返回每列的总和）

Sub sumcols()

Dim blocks As Integer
Dim Fa As Long, Fb As Long, Fc As Long, Fd As Long, Fe As Long
Dim i As Long, j As Long
Dim currange As Range

blocks = 9

For i = 2 To Sheets("sheet1").Range("A1048576").End(xlUp).Row Step blocks + 1 'A1048576' will need to be changed if excel version older than '07
    'get sums for columns a through e for block starting with row i

    For j = 1 To 5 'iterate through columns

    'get range to sum (first range will be A2:A12)
    Set currange = Sheets("sheet1").Range(Sheets("sheet1").Cells(i, j), Sheets("sheet1").Cells(i + blocks, j))

    Fa = Application.WorksheetFunction.Sum(currange) 'Fa will return the sum for each column for each block

    'print values to immediate window
    Debug.Print Fa

    Next j

Next i

End Sub
