VBA删除具有多列选择的空单元格

Question

我在寻找潜在问题的可能解决方案时遇到了一些麻烦。我正在使用 VBA 为我的主管编写一个宏，以便她只需单击分配给该宏的按钮并按照说明操作即可获取她需要的数据。我遇到的问题是，当宏粘贴数据时，如果用户选择多列，则无法删除空单元格。

Sub DataPull()
' Written by Agony
' Data Pull macro
Dim rng1 As Range
Dim rng2 As Range
Dim chc1
Dim chc2
Dim wb1 As Workbook
Dim wb2 As Workbook

'Choose file to get data
chc1 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select file to pull data from")
If chc1 = False Then Exit Sub

'Choose file to paste data
chc2 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select file to paste data to")
If chc2 = False Then Exit Sub

'Open first file and copy range
Set wb1 = Workbooks.Open(chc1)
Set rng1 = Application.InputBox("Select cells to transfer", "Selection", "Use your mouse/pointer to select the cells", Type:=8)
rng1.Copy
wb1.Close SaveChanges:=False

'Open second file and paste with specs
Set wb2 = Workbooks.Open(chc2)
Set rng2 = Range("A1")
rng2.PasteSpecial
With Selection.Interior
    .Pattern = xlNone
    .TintAndShade = 0
    .PatternTintAndShade = 0
End With
With Selection.Font
    .Name = "Cambria"
    .Size = 12
    .TintAndShade = 0
End With

Selection.Borders(xlDiagonalDown).LineStyle = xlNone
Selection.Borders(xlDiagonalUp).LineStyle = xlNone
Selection.Borders(xlEdgeLeft).LineStyle = xlNone
Selection.Borders(xlEdgeTop).LineStyle = xlNone
Selection.Borders(xlEdgeBottom).LineStyle = xlNone
Selection.Borders(xlEdgeRight).LineStyle = xlNone
Selection.Borders(xlInsideVertical).LineStyle = xlNone
Selection.Borders(xlInsideHorizontal).LineStyle = xlNone

'Loop to delete empty cells
Dim i As Long
Dim rows As Long
Dim rng3 As Range
Set rng3 = ActiveSheet.Range("A1:Z50")
rows = rng3.rows.Count
For i = rows To 1 Step (-1)
    If WorksheetFunction.CountA(rng3.rows(i)) = 0 Then rng3.rows(i).Delete
Next

wb2.Activate
MsgBox ("Macro Complete")
End Sub

如上所示，该范围目前是暂定的。如果用户选择具有多列的范围，我希望该函数删除空单元格。我尝试过对单元格使用 Len ，但这似乎也不起作用。任何帮助是极大的赞赏。谢谢!

当源工作簿关闭时，我认为您无法使用 .Copy 和 .Paste。

我认为当工作簿关闭时，您复制的任何内容都会丢失。

因此，解决您的问题的一个可能的解决方案是在宏末尾关闭 wb1，而不是在复制命令之后立即关闭。

因此将 wb1.Close SaveChanges:=False 移动到此 block 之后

...
'Open second file and paste with specs
Set wb2 = Workbooks.Open(chc2)
Set rng2 = Range("A1")
rng2.PasteSpecial
With Selection.Interior
    .Pattern = xlNone
    .TintAndShade = 0
    .PatternTintAndShade = 0
End With
With Selection.Font
    .Name = "Cambria"
    .Size = 12
    .TintAndShade = 0
End With
wb1.Close SaveChanges:=False ' moved it here
...

试试这个子程序，看看这是否是你想要的。它的作用是找到电子表格中使用的最后一列和每列中的最后一行。从每列的最后一行迭代并删除所有空单元格，将填充的单元格向上移动。

Sub DeleteAllAtOnce()
Application.ScreenUpdating = False
    Dim lastColumn As Long
    Dim lastRow As Long

    lastColumn = ActiveSheet.UsedRange.Columns.Count

    Dim i As Long, j As Long
    Dim cell As Range
    For i = lastColumn To 1 Step -1
        lastRow = Cells(rows.Count, i).End(xlUp).Row
        For j = lastRow To 1 Step -1
            Set cell = Cells(j, i)
            If IsEmpty(cell) Then cell.Delete shift:=xlUp
        Next j
    Next i
    Application.ScreenUpdating = True
End Sub
