Sub AddLineNumbers() Dim rng As Range Dim cell As Range Dim lines() As String Dim i As Integer Set rng = Application.Selection ' 选择要操作的单元格范围 ' 遍历每个单元格 For Each cell In rng If cell.Value <> "" Then lines = Split(cell.Value, Chr(10)) ' 以换行符分割文本为数组 For i = LBound(lines) To UBound(lines) ' 在每一段文字前加上序号，并使用换行符重新组合文本 lines(i) = i + 1 & " " & lines(i) Next i cell.Value = Join(lines, Chr(10)) ' 重新组合文本为单元格值 End If Next cell End Sub

你提供的代码看起来是正确的，它实现了在单元格内换行并加上序号的功能。你只需要将这段代码复制到 Excel 的 VBA 编辑器中，然后按照上述步骤执行宏即可。

请确保在运行宏之前已经选择了要操作的单元格范围，并注意确认你的文本段落是以换行符（Chr(10)）分隔的。

把下面代码的定义变量：Dim rng As Range Set rng = Selection For Each Cell In rng If Cell.MergeCells Then Set rng = Union(rng, Cell.MergeArea) End If

可以将代码定义变量的部分修改为：

Dim rng As Range
Set rng = Selection

Dim Cell As Range

For Each Cell In rng
    If Cell.MergeCells Then
        Set rng = Union(rng, Cell.MergeArea)
    End If
Next Cell

这样就对变量 Cell 进行了定义，并且在 For Each 循环中使用了 Next Cell 语句来结束循环。

Sub Katana1994() Dim doc1 As Document Dim rng As Range Dim chapterStart As Long Dim chapterEnd As Long Dim chapterTitle As String Dim chapterIndex As Integer Dim newDoc As Document Set doc1 = ActiveDocument chapterIndex = 1 For i = 1 To doc1.Paragraphs.Count Set rng = doc1.Paragraphs(i).Range If rng.Text Like "第*篇*" Or rng.Text Like "*、*" Then If chapterStart > 0 Then chapterEnd = rng.Start - 1 doc1.Range(chapterStart, chapterEnd).Select Selection.Copy Set newDoc = Documents.Add() newDoc.Content.Paste newDoc.SaveAs "Chapter" & chapterIndex & " - " & chapterTitle & ".docx" newDoc.Close chapterIndex = chapterIndex + 1 End If chapterTitle = rng.Text chapterStart = rng.End End If Next i End Sub这段代码依然在第一行显示未声明变量

这段代码中的错误是因为缺少了 "Option Explicit" 语句。可以在代码的最上面添加 "Option Explicit"，它可以强制要求在使用变量之前必须先声明它们，从而防止因为未声明变量而导致的错误。

修改后的代码如下：

Option Explicit

Sub Katana1994()
    Dim doc1 As Document
    Dim rng As Range
    Dim chapterStart As Long
    Dim chapterEnd As Long
    Dim chapterTitle As String
    Dim chapterIndex As Integer
    Dim newDoc As Document
    
    Set doc1 = ActiveDocument
    chapterIndex = 1
    
    For i = 1 To doc1.Paragraphs.Count
        Set rng = doc1.Paragraphs(i).Range
        
        If rng.Text Like "第*篇*" Or rng.Text Like "*、*" Then
            If chapterStart > 0 Then
                chapterEnd = rng.Start - 1
                doc1.Range(chapterStart, chapterEnd).Select
                Selection.Copy
                Set newDoc = Documents.Add()
                newDoc.Content.Paste
                newDoc.SaveAs "Chapter" & chapterIndex & " - " & chapterTitle & ".docx"
                newDoc.Close
                chapterIndex = chapterIndex + 1
            End If
            
            chapterTitle = rng.Text
            chapterStart = rng.End
        End If
    Next i
End Sub
