Excel 宏可以工作,但速度太慢
我发现这个宏可以完成这项工作,但它需要很长时间才能执行。我想把它移到第4行到第350行,而不是所有的行。另外,我希望它不询问哪张表,而是执行表名数据。宏用于删除空行Excel 宏可以工作,但速度太慢,excel,vba,Excel,Vba,我发现这个宏可以完成这项工作,但它需要很长时间才能执行。我想把它移到第4行到第350行,而不是所有的行。另外,我希望它不询问哪张表,而是执行表名数据。宏用于删除空行 Sub DeleteBlankRows() Dim wks As Worksheet Dim lngLastRow As Long, lngLastCol As Long, lngIdx As Long, _ lngColCounter As Long Dim blnAllBlank As B

子删除blankrows()
将工作作为工作表
暗淡的lngLastRow和长的lngLastCol和长的lngIdx_
lngColCounter尽可能长
将空白设置为布尔值
Dim UserInputSheet作为字符串
UserInputSheet=Application.InputBox(“输入要从中删除空行的工作表的名称”)
Set wks=工作表(UserInputSheet)
有工作
'现在我们的工作表已经定义,我们将找到最后一行和最后一列
lngLastRow=.Cells.Find(What:=“*”,LookIn:=xlFormulas_
搜索顺序:=xlByRows_
搜索方向:=xlPrevious).行
lngLastCol=.Cells.Find(What:=“*”,LookIn:=xlFormulas_
SearchOrder:=xlByColumns_
SearchDirection:=xlPrevious).列
'因为我们需要删除行,所以我们从底部开始向上移动
对于LNGIX=lngLastRow到1步骤-1
'首先设置一个标志以立即停止检查
'如果单元格不为空并初始化列计数器
blnAllBlank=True
lngColCounter=2
'标记为真时,从左到右检查单元格
“我们就在最右边的一列
当blnAllBlank和LNGCOLTER为空时,如果该行中的所有单元格都为空,则似乎要删除该行
Dim rng As Range
Dim i As Long
Dim MyRow As Range, DeleteRange As Range
Dim MiF As WorksheetFunction
Set MiF = WorksheetFunction
Set rng = Range("C7:M34") 'define range here
For i = 1 To rng.Rows.Count
If MiF.CountA(rng.Rows(i)) = 0 Then
If DeleteRange Is Nothing Then
Set DeleteRange = rng.Rows(i) 'first time, we can't use Union
Else
'we unite all complete blank rows into one final "big" range
Set DeleteRange = Union(DeleteRange, rng.Rows(i))
End If
End If
Next i
'we delete if something is found
If Not DeleteRange Is Nothing Then DeleteRange.EntireRow.Delete
'clear variables
Set DeleteRange = Nothing
Set rng = Nothing
Set MiF = Nothing
实际代码检查datarange中每行和每列的每个单元格
您可以通过检查整行是否为空来提高速度。例如:
黄色单元格是空白单元格
红细胞是完整的空白行(该行中的所有细胞都是空白)
此代码将删除红色行,这意味着它将删除整行,但仅当所有单元格都为空时
Dim rng As Range
Dim i As Long
Dim MyRow As Range, DeleteRange As Range
Dim MiF As WorksheetFunction
Set MiF = WorksheetFunction
Set rng = Range("C7:M34") 'define range here
For i = 1 To rng.Rows.Count
If MiF.CountA(rng.Rows(i)) = 0 Then
If DeleteRange Is Nothing Then
Set DeleteRange = rng.Rows(i) 'first time, we can't use Union
Else
'we unite all complete blank rows into one final "big" range
Set DeleteRange = Union(DeleteRange, rng.Rows(i))
End If
End If
Next i
'we delete if something is found
If Not DeleteRange Is Nothing Then DeleteRange.EntireRow.Delete
'clear variables
Set DeleteRange = Nothing
Set rng = Nothing
Set MiF = Nothing
执行代码后,输出如下所示
在这个循环中,LNGIX=lngLastRow的到第1步-1
将lngLastRow
定义为350,将1
定义为4
,因此它从350
运行到4
,而不是设置工作表(UserInputSheet)
写下工作表名设置工作表=工作表(“Sheet1”)
您希望在上执行它。如果您只想删除空行,为什么不对工作表进行排序?这将将空白行移到底部,从而“删除”它们。或者Set wks=ActiveSheet
@Andreas,因为排序将对数据进行排序,如果这不是他想要的,则会把一切都搞糟。排序数据并不是删除完全不同的空白。在不了解任何工作表或数据的情况下,排序似乎是完成工作的更简单方法。我更愿意让OP来设置数据的OK/Not OK边界。我尝试了PEH解决方案,但什么都不做。它完成了工作,部分空白行仍然存在!你说的部分是什么意思?它可以做前3张桌子,但不能做下2张。嗨,我找到了原因,它工作了!谢谢
