loops - 向 Excel 的 vba 代码添加循环

Question

我对vba知之甚少，希望有人能帮助我。

我下面有以下代码，它“用上面的值填充列中的空白单元格”并且工作正常。

我需要在不连续的列上使用它。 有没有办法向其添加循环，以便它在 [B D H I] 列上运行？

我试图解决这个问题，但没有得到任何结果

谢谢

您可以尝试以下方法:

Sub FillColBlanks(sColRange as string)

'by Dave Peterson  2004-01-06
'fill blank cells in column with value above
'http://www.contextures.com/xlDataEntry02.html
Dim wks As Worksheet
Dim rng As Range 
Dim Lastrow As Long
Dim col As Long

Set wks = ActiveSheet
With wks
   'col = ActiveCell.Column
   'or
   col = .Range(sColRange).Column

   Set rng = .UsedRange  'try to reset the lastcell
   Lastrow = .Cells.SpecialCells(xlCellTypeLastCell).Row
   Set rng = Nothing
   On Error Resume Next
   Set rng = .Range(.Cells(2, col), .Cells(Lastrow, col)) _
                  .Cells.SpecialCells(xlCellTypeBlanks)
   On Error GoTo 0

   If rng Is Nothing Then
       MsgBox "No blanks found"
       Exit Sub
   Else
       rng.FormulaR1C1 = "=R[-1]C"
   End If

   'replace formulas with values
   With .Cells(1, col).EntireColumn
       .Value = .Value
   End With

End With

End Sub

所以你可以这样调用该过程:

Call FillColBlanks("B1")
Call FillColBlanks("D1")
Call FillColBlanks("H1")
Call FillColBlanks("I1")
