以编程方式在Excel中选择其他工作表先例或依赖项

Question

在Excel中， Ctrl + [或]有时会直接切换到另一个工作表以显示该工作表中的先例或从属项。

我想以编程方式进行编程，因为我想获得一系列单元格的先例（或依赖项）。

Range.Dependents和Range.Precedents还有其他问题 ，但那里的解决方案并没有解决表外问题。

Answer 1

马克做了一些不错的工作，但是这个宏完全不会在同一张纸上出现'凹陷而失败，当有来自多张纸的凹痕时，因为无法从多个单张纸单元创建选择。

我个人需要所有这些功能来取代“Ctrl + [”和“Ctrl +]”快捷方式功能，以跳转到先例和家属。 不幸的是，这些快捷方式在国际键盘上完全无法使用，其中这些方括号隐藏在AltGr（右Alt）组合下，Excel不允许Ctrl + AltGr + 8和Ctrl + AltGr + 8给出相同的结果，并且还有无法重新映射默认快捷方式。

所以我稍微改进了Mark的代码以修复这些问题并从代码中删除弹出消息，因为我应该知道自己是否无法选择所有'凹痕，但我希望函数能够顺利运行而不必单击OK all时间。 因此，该函数只是跳转到工作表中，该工作表首先在公式中链接。

我希望这对其他人也有用。

仍然困扰我的唯一事情是，当Application.ScreenUpdating = False Avoids跳过工作表和工作簿时，箭头仍然保持闪烁。 有什么办法可以避免这个吗

经过一段时间的谷歌搜索后，我发现它在2003年得到了解决。

但是我使用了这里的代码。

问题是Dependents和Precedents是Range属性，它不能引用多个工作表。

该解决方案使用NavigateArrow来定位交叉表的凹痕。

这是我的代码：

Option Explicit

Private Sub GetOffSheetDents(ByVal doPrecedents As Boolean)

Dim c As Range
Dim results As Range
Dim r As Range
Dim sheet As Worksheet
Dim extra As Boolean

For Each c In Application.Intersect(ActiveSheet.UsedRange, Selection)
    Set r = oneCellDependents(c, doPrecedents)
    If Not r Is Nothing Then
        If r.Worksheet Is ActiveSheet Then
            ' skip it
        ElseIf sheet Is Nothing Then
            Set sheet = r.Worksheet
            Include results, r
        ElseIf Not sheet Is r.Worksheet Then
            If Not extra Then
                extra = True
                MsgBox "More than one external sheet in " & IIf(doPrecedents, "Precedents", "Dependents") & ". Only displaying first sheet."
            End If
        Else
            Include results, r
        End If
    End If
Next

If results Is Nothing Then
    Beep
Else
    results.Worksheet.Activate
    results.Select
End If
End Sub

Sub GetOffSheetDependents()

GetOffSheetDents False

End Sub

Sub GetOffSheetPrecedents()

GetOffSheetDents True

End Sub

Private Function Include(ByRef ToUnion As Range, ByVal Value As Range) As Range
If ToUnion Is Nothing Then
    Set ToUnion = Value
Else
    Set ToUnion = Application.Union(ToUnion, Value)
End If
Set Include = ToUnion
End Function

Private Function oneCellDependents(ByVal inRange As Range, Optional doPrecedents As Boolean) As Range

Dim inAddress As String, returnSelection As Range
Dim i As Long, pCount As Long, qCount As Long

If inRange.Cells.Count <> 1 Then Error.Raise 13

Rem remember selection
Set returnSelection = Selection
inAddress = fullAddress(inRange)

Application.ScreenUpdating = False
With inRange
    .ShowPrecedents
    .ShowDependents
    .NavigateArrow doPrecedents, 1
    Do Until fullAddress(ActiveCell) = inAddress
        pCount = pCount + 1
        .NavigateArrow doPrecedents, pCount
        If ActiveSheet.Name <> returnSelection.Parent.Name Then

            Do
                qCount = qCount + 1
                .NavigateArrow doPrecedents, pCount, qCount
                Include oneCellDependents, Selection
                On Error Resume Next
                .NavigateArrow doPrecedents, pCount, qCount + 1
                If Err.Number <> 0 Then _
                    Exit Do
                On Error GoTo 0
            Loop
            On Error GoTo 0
            .NavigateArrow doPrecedents, pCount + 1
        Else
            Include oneCellDependents, Selection
            .NavigateArrow doPrecedents, pCount + 1

我发现了kaidobor版本的Mark Hurd的代码正是我所需要的。 我编写了一个包装器来记录所选单元格中的所有依赖项，并将它们插入到新表中。 我的代码只是调用kaidobor的代码并记录结果。

我的用例：我有一个复杂的电子表格（由其他人编写），我需要清理。 我想删除一些看似不必要但仍想知道在删除工作表之前我将破坏公式的工作表。 这将创建一个索引，显示其他工作表中引用的所有单元格。
