excel 仅选择一列中的前800个可见单元格,即使可见的筛选单元格超过800个也是如此

我需要一个VBA代码,这将允许我选择和复制自定义数量的可见行只。例如:我过滤了一列数据,所有可见单元格的计数为1000。但是,我只想复制1000个可见单元格中的前800个可见单元格。

一种方法是使用SpecialCells(xlCellTypeVisible)获取所有可见单元格,然后使用Application.Union逐个循环并收集它们,以将它们限制到所需的数量。

Option Explicit

Public Sub Example()
    Dim Top800Cells As Range
    Set Top800Cells = GetTopVisibleRows(OfRange:=Range("A:A"), TopAmount:=800)
    
    Top800Cells.Select
End Sub

Public Function GetTopVisibleRows(ByVal OfRange As Range, ByVal TopAmount As Long) As Range
    Dim VisibleCells As Range
    Set VisibleCells = OfRange.SpecialCells(xlCellTypeVisible)
    
    If VisibleCells Is Nothing Then
        Exit Function
    End If
    
    Dim TopCells As Range
    Dim Count As Long
    Dim Row As Range
    
    For Each Row In VisibleCells.Rows
        If TopCells Is Nothing Then
            Set TopCells = Row
        Else
            Set TopCells = Application.Union(TopCells, Row)
        End If
        Count = Count + 1
        If Count = TopAmount Then Exit For
    Next Row
    
    Set GetTopVisibleRows = TopCells
End Function

如果你想在公式中使用它作为UDF(用户定义函数),SpecialCells(xlCellTypeVisible)会失败(参见SpecialCells(xlCellTypeVisible) not working in UDF),你需要自己检查可见性:

Public Function GetTopVisibleRows(ByVal OfRange As Range, ByVal TopAmount As Long) As Range
    Dim TopCells As Range
    Dim Count As Long
    Dim Row As Range
       
    For Each Row In OfRange.Rows
        If Not Row.EntireRow.Hidden Then
            If TopCells Is Nothing Then
                Set TopCells = Row
            Else
                Set TopCells = Application.Union(TopCells, Row)
            End If
            Count = Count + 1
            If Count = TopAmount Then Exit For
        End If
    Next Row
    
    Set GetTopVisibleRows = TopCells
End Function

复制SpecialCells(xlCellTypeVisible)的前 n

  • 通常对更多列执行此操作,如代码中所示。
  • 要仅将其应用于列A,请将Set rg = ws.Range("A1").CurrentRegion替换为
Set rg = ws.Range("A1").CurrentRegion.Columns(1)

假设标题在第一工作表行中。

  • 简而言之,它在各行之间循环(rrg)的面积范围的(arg)(MultiRangedvrg)每行计数(r)而当它击中“标记”时(DataRowsCount),则它使用此行(Set SetMultiRangeRow = rrglrrg)和第一行(frrg)作为range属性中的参数,以设置所需的范围,并重新应用相同类型的SpecialCells,以最终引用所需数量的行。
