Excel VBA宏根据条件对行进行分组

Question

我正在尝试创建一个宏，该宏根据 A 列中是否有值对行进行分组。一些没有值的单元格可能仍然有一个空文本字符串，所以最好使用长度之类的东西大于 2 作为分组的条件，而不仅仅是空白。应用宏的范围是从第 3 行到数据集的最后一行（或者如果需要定义范围，到第 3000 行就足够了）。例如，如果 A4 有一个值，A10 有一个值，那么第 5 行到第 9 行应该成为一个组。我发现一些代码只是谷歌搜索，但我无法正确应用它，所以我宁愿从头开始。提前致谢！

Answer 1

试试这个 如果空单元格为空白，则适用于我

sub ashGrp()

Dim rng As Range
Dim blankRange As Range
Dim grp As Range
Set rng = Range("a3", Cells(Rows.Count, 1).End(xlUp))
Set blankRange = rng.SpecialCells(xlCellTypeBlanks)

For Each grp In blankRange
    grp.Rows.Group
Next

end sub

如果您需要对文本或空白进行分组，那么这个联合代码就可以解决问题

Sub ashGrp()

    Dim rng As Range
    Dim blankRange As Range
    Dim grp As Range
    Dim txtRange As Range
    Dim unionRange As Range

    Set rng = Range("a3", Cells(Rows.Count, 1).End(xlUp))
    Set blankRange = rng.SpecialCells(xlCellTypeBlanks)
    Set txtRange = rng.SpecialCells(xlCellTypeConstants, xlTextValues)
    Set unionRange = Union(blankRange, txtRange)

    For Each grp In unionRange
    grp.Rows.Group
    Next


End Sub

你可以试试这个。这是这篇文章中缩小的宏：https://stackoverflow.com/a/14967281/6201755

Public Sub GroupCells()
    Dim myRange As Range
    Dim rowCount As Integer, currentRow As Integer
    Dim firstBlankRow As Integer, lastBlankRow As Integer
    Dim currentRowValue As String

    'select range based on given named range
    Set myRange = Range("A3:A3000")
    rowCount = Cells(Rows.Count, myRange.Column).End(xlUp).Row

    firstBlankRow = 0
    lastBlankRow = 0
    'for every row in the range
    For currentRow = 1 To rowCount
        currentRowValue = Cells(currentRow, myRange.Column).Value

        If (IsEmpty(currentRowValue) Or currentRowValue = "") Then
            'if cell is blank and firstBlankRow hasn't been assigned yet
            If firstBlankRow = 0 Then
                firstBlankRow = currentRow
            End If
        ElseIf Not (IsEmpty(currentRowValue) Or currentRowValue = "") Then
            If firstBlankRow <> 0 Then
                'if firstBlankRow is assigned and this row has a value
                'then the cell one row above this one is to be considered
                'the lastBlankRow to include in the grouping
                lastBlankRow = currentRow - 1
            End If
        End If

        'if first AND last blank rows have been assigned, then create a group
        'then reset the first/lastBlankRow values to 0 and begin searching for next
        'grouping
        If firstBlankRow <> 0 And lastBlankRow <> 0 Then
            Range(Cells(firstBlankRow, myRange.Column), Cells(lastBlankRow, myRange.Column)).EntireRow.Select
            Selection.Group
            firstBlankRow = 0
            lastBlankRow = 0
        End If
    Next
End Sub
