做这样的事情？如果所需的列数发生变化，这将找到连续块中的最后一列。
Sub Delete_missing_vals()
Dim myLastRow As Long, myLastCol as Long
Dim i As Long, j as long
Application.ScreenUpdating = False
' Find last row & col
myLastRow = Cells(Rows.Count, "A").End(xlUp).Row
myLastCol = Cells(1,"A").End(xlToRight).Column
' Loop through range
For i = 1 To myLastRow
For j = 1 to MylastCol
If Cells(i, j) = -99 Or Cells(i, j) = -77 Or Cells(i, j) = -66 Then
Cells(i, j).ClearContents
End If
Next j
Next i
Application.ScreenUpdating = True
End Sub

如果我做对了，你将按升序测试从 A 到 ED 的所有列。这使得5x26 + 4 = 134列按升序排列。
在行循环中创建另一个循环，从1循环到134.
For i = 1 To myLastRow
For j=1 to 134
If Cells(i, j).Value = -99 Or Cells(i, j).Value = -77 Or Cells(i, j).Value = -66 Then Range(Cells(i, j), Cells(i, j)).ClearContents
Next j
Next i

这应该可以解决问题。您可以执行与计算最后一行类似的操作，以便在需要时计算最后一列。
Sub Delete_missing_vals()
Dim myLastRow As Long
Dim i As Long
Application.ScreenUpdating = False
' Find last row
myLastRow = Cells(Rows.Count, "A").End(xlUp).Row
' Loop through range
For i = 1 To myLastRow
For j = 1 To 134
If Cells(i, j).Value = -99 Or Cells(i, j).Value = -77 Or Cells(i, j).Value = -66 Then Cells(i, j).ClearContents
Next j
Next i
Application.ScreenUpdating = True
End Sub

尝试这样的事情：
Sub Delete_missing_vals()
Dim myLastRow As Long
Dim i As Long
Dim myVariant as Variant
set myVariant = Array("A","B","C","D","E","F","G","ETC")
Application.ScreenUpdating = False
' Find last row
myLastRow = Cells(Rows.Count, "A").End(xlUp).Row
' Loop through range
For i = 1 To myLastRow
for col = lbound(myVariant) to Ubound(myVariant)
If Cells(i, myVariant(col)).Value = -99 Or Cells(i, myVariant(col)).Value = -77 Or Cells(i, myVariant(col)).Value = -66 Then Range(Cells(i, myVariant(col)), Cells(i, myVariant(col))).ClearContents
next col
next i
Application.ScreenUpdating = True
End Sub
但是可能还有其他更好的方法可以让它发挥作用。不过，你可以在数组中手动选择列，这是一个令人生畏的奖励：）

我会这样做：
Sub Delete_missing_vals()
Dim cell As Range
Dim myRange As Range
Application.ScreenUpdating = False
Set myRange = Cells(1, 1).CurrentRegion
For Each cell In myRange
With cell
If .Value = -99 Or .Value = -77 Or .Value = -66 Then
.ClearContents
End If
End With
Next cell
Application.ScreenUpdating = True
End Sub

看起来你可以通过迭代Used Range中的所有单元格来做到这一点。这类似于Tackgnol的回答
Sub IterateSheetCells()
Dim cell As Range
For Each cell In ActiveSheet.UsedRange.Cells
With cell
If .Value = -99 OR .Value = -77 OR .Value = -66 Then
.ClearContents
End If
End With
Next
End Sub
