Question

我正在尝试在Excel VBA中创建代码，以找到表中彩色行的开头（单元格地址）和结束（单元格地址）。该表是时间轴（水平轴 - 日期，垂直轴 - 常规文本）。彩色行都不会在第一列中开始，而是从不同的列开始。有什么帮助吗？

这是怎么回事？

Sub findColoredRows()
Dim startCol As Integer, endCol As Integer, o As Integer
Dim ws            As Worksheet
Dim i As Integer, k As Integer
Dim startRow As Long, endRow As Long
Dim cellColor As String, noColor As String
Dim cel           As Range

noColor = -4142              ' this is the color index of NO coloring

k = 3

Set ws = ActiveSheet
With ws
    startRow = .Cells(1, 3).End(xlDown).Row
    startCol = .Cells(1, 3).Column
    Do While startRow > 100  ' I assume your table starts before row 100.  So, if there's no data before row 100, check next column
        k = k + 1
        startRow = .Cells(1, k).End(xlDown).Row
        startCol = k
    Loop

    'Now, we have our starting row - get end row.
    endRow = .Cells(startRow, k).End(xlDown).Row

    endCol = .Cells(startRow, startCol).End(xlToRight).Column
    Debug.Print "Start row: " & startRow & ", start column: " & startCol

    ' How many non colored cells is there in our range?
    Dim noColorCells As Integer
    For Each cel In .Range(.Cells(startRow, startCol), .Cells(endRow, endCol))
        If cel.Interior.ColorIndex = noColor Then
            noColorCells = noColorCells + 1
        End If
    Next cel
    Debug.Print "There are " & noColorCells & " non colored cells."

    .Cells(startRow - 1, endCol + 2).Value = "Start Date"
    .Cells(startRow - 1, endCol + 3).Value = "End Date"

    'reDim the array to fit the colored cells
    ReDim tDates(1 To noColorCells + 1)
    i = 1                    'index starts at 1, so set this to 1

    For k = startRow To endRow
        For o = startCol To endCol
            If .Cells(k, o).Interior.ColorIndex = noColor And .Cells(k, endCol + 2) = "" Then
                .Cells(k, endCol + 2).Value = .Cells(k, o).Value
            ElseIf .Cells(k, o).Interior.ColorIndex = noColor And .Cells(k, endCol + 2) Then
                i = i + i
                .Cells(k, endCol + 3).Value = .Cells(k, o).Value
            End If
            ' i = i + 1
        Next o

        i = i + 1
    Next k

End With

MsgBox ("Done!")

End Sub

此子将找到任何彩色单元格的地址。如果您可以通过“在表格中找到彩色行的开头和结尾”来解释更多含义。我可以调整一下。您可以发布样本表的图像吗？

编辑：根据下面的讨论，如果表格中并不总是有数据，但是你想要彩色单元格的列，请尝试这样做：

Sub findColoredBGCells()
Dim startRow As Integer, endRow As Integer, i As Integer, k As Integer, startCol As Integer, endCol As Integer
Dim cellColor As String, noColor As String
Dim ws As Worksheet

Set ws = ActiveSheet
noColor = -4142

With ws
    'Get the starting row
    startRow = .Cells(1, 1).End(xlDown).Row
    endRow = .Cells(startRow, 1).End(xlDown).Row

    ' Since we know where the names start and end (less ONE for the "Names" part), let's count how many names we have
    Dim noNames As Integer
    noNames = endRow - startRow
    If Not IsEmpty(.Cells(1, 1)) Then ' Get the first used column with data
        startCol = 1
    ElseIf IsEmpty(.Cells(1, 1)) Then
        startCol = .Cells(1, 1).End(xlToRight).Column
    End If

    endCol = .Cells(1, startCol).End(xlToRight).Column

    'Now we have our range, let's use it to loop for blank cells, and add those to an array
    Dim coloredCells() As Variant
    ReDim coloredCells(1 To noNames, 2)
    Dim rng As Range, cel As Range
    Set rng = .Range(.Cells(startRow, startCol), .Cells(endRow, endCol))
    'rng.Select

    'Now, count how many cells are not blank background
    Dim cnt As Integer, celRow As Integer, lastCelRow As Integer
    i = 1

    lastCelRow = 2
    For Each cel In rng
        cel.Select
        celRow = cel.Row
        If cel.Row <> lastCelRow Then 'This is so we can change the first dimension in the array
            k = k + 1
            coloredCells(k, 0) = .Cells(cel.Row, 1).Value
            i = 1
           ' i = i + 1
        End If

        If cel.Interior.ColorIndex <> noColor Then
            cnt = cnt + 1
            If i > 2 Then i = 2 'Since it's only two dimensions we need, only go up to '1'
           ' ReDim Preserve coloredCells(noNames, i) 'resize the array to hold the new column
            coloredCells(k, i) = .Cells(1, cel.Column).Value
            i = i + 1
        End If
        lastCelRow = celRow
    Next cel

For k = 1 To UBound(coloredCells)
        Debug.Print coloredCells(k, 0) & " Start Date: " & coloredCells(k, 1) & ", end date: " & coloredCells(k, 2) & "."
        .Cells(2 + k, 2).Value = coloredCells(k, 1)
        .Cells(2 + k, 3).Value = coloredCells(k, 2)
Next k

End With

MsgBox ("Done!")

End Sub
