我在当前的工作簿中使用了几千行。 但是有几百行是完全空白的。
如何选择每一行（仅完全空白的那一行）并删除它们？
答案 0 :(得分：9)
有两种方法可以做到：
<强> 1。使用VBA：
有一个VBA脚本here in this link。使用第一个脚本，我的意思是 DeleteBlankRows 。
您也可以从here复制相同的代码。
使用方法：
Copy the code.
In Excel press Alt + F11 to enter the VBE.
Press Ctrl + R to show the Project Explorer.
Insert -> Module.
Paste code.
Save and Exit VBE.
运行代码：
Select the column with blank rows.
Press Alt + F8 to open the macro dialog box.
Select DeleteBlankRows
Click Run.
<强> 2。没有VBA：
只需在此处查看link即可。这很容易，所以不需要再解释一下。

我会在这里粘贴代码，以防链接在将来死亡。
只是注意，第二部分“没有VBA”将不符合原始问题的要求，因为它将删除包含空白单元格的行，但不完全空白。
以下是接受答案第一个链接的代码。
Sub DeleteBlankRows(Optional WorksheetName As Variant)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' DeleteBlankRows
' This function will delete all blank rows on the worksheet
' named by WorksheetName. This will delete rows that are
' completely blank (every cell = vbNullString) or that have
' cells that contain only an apostrophe (special Text control
' character).
' The code will look at each cell that contains a formula,
' then look at the precedents of that formula, and will not
' delete rows that are a precedent to a formula. This will
' prevent deleting precedents of a formula where those
' precedents are in lower numbered rows than the formula
' (e.g., formula in A10 references A1:A5). If a formula
' references cell that are below (higher row number) the
' last used row (e.g, formula in A10 reference A20:A30 and
' last used row is A15), the refences in the formula will
' be changed due to the deletion of rows above the formula.

我发现当前答案的时间过长。
我下面的代码逐一检查所有使用的范围行，如果它们为空，则将其删除。
Public Sub DeleteEmptyRows()
Dim SourceRange As Range
Dim EntireRow As Range
On Error Resume Next
Set SourceRange = Sheet1.UsedRange
If Not (SourceRange Is Nothing) Then
Application.ScreenUpdating = False
For i = SourceRange.Rows.Count To 1 Step -1
Set EntireRow = SourceRange.Cells(i, 1).EntireRow
If Application.WorksheetFunction.CountA(EntireRow) = 0 Then
EntireRow.Delete
End If
Next
Application.ScreenUpdating = True
End If
End Sub
