VBA：仅用于背景填充单元格的输入SUM公式

Question

我是VBA的新手，我正在尝试编写一段代码，将总和公式插入到蓝色单元格中，然后总结到下一个蓝色单元格（参见附件）。我需要这样做的原因是因为这将是一个模板，用于将文本文件插入此电子表格的用户，所以我希望它格式化单元格并添加公式，这样如果他们决定添加一个新行，它将自动重新计算总数。任何帮助将不胜感激！！！如果您需要更多细节，请告诉我们！

不确定您的其他数据如何通过屏幕截图，但这样的事情应该有效。我试图尽可能彻底地评论，以帮助解释它是如何完成的，这样你就可以更多地了解VBA的工作原理。

Sub SumBetweenBlues()

'declare your variables
Dim ws As Worksheet
Dim x As Long, y As Long, endRow As Long, startSum As Long, endSum As Long, xBlue as Long
Dim colL As String

'set the worksheet to work with (this can be changed if necessary)
Set ws = ActiveWorkbook.ActiveSheet

'set the color of blue to check for
xBlue = RGB(201, 234, 236)

'column where the sums will be put (C)
Const sumCol As Integer = 3

'first row
Const startRow As Integer = 2

'turns the column number into a letter for the formula
colL = colLetter(sumCol)

'determines the last used row and goes a bit past it since blues may/may not be blank themselves
endRow = ws.Cells(ws.Rows.Count, sumCol).End(xlUp).Row + 50

'loop through all the cells in the sum column
For x = startRow To endRow

    'checks if the cell is blue
    If ws.Cells(x, sumCol).Interior.Color = xBlue Then

        'set the start of the sum range to the cell after the blue cell
        startSum = x + 1

        'find the end of the sum range
        For y = startSum + 1 To endRow

            'checks if the cell is also blue
            If ws.Cells(y, sumCol).Interior.Color = xBlue Then

                'sets the end of the sum range to the cell before the blue cell
                endSum = y - 1
                Exit For

            End If
        Next y

        'so long as an endsum area was found, set the formula in the blue cell
        If endSum <> 0 Then
            ws.Cells(x, sumCol).Formula = "=SUM(" & colL & startSum & ":" & colL & endSum & ")"
        End If

        'skip all the non-blue cells inbetween
        x = y - 1

        'reset the start/end of the sum area
        startSum = 0
        endSum = 0

    End If

Next x

End Sub

'---------------------------------------------------------------------------

Function colLetter(intCol As Integer) As String
'this function turns column numbers into letters
Dim vArr: vArr = Split(Cells(1, intCol).Address(True, False), "$"): colLetter = vArr(0)
End Function
