一、需要达到的效果

文档中样式“标题 1”到“标题 9”分别链接到相应级别列表

各级列表与文字间不用默认的制表符连接，而用空格连接

完成对激活文档（当前文档）光标所选区域符合要求的标题段落（样式为“标题 n”的段落）应用此列表

多级列表目标效果

二、代码

Sub 多级列表()
    Dim numFormatStr As String
    Dim i As Byte
    Dim doc As Document
    Dim listTemp As Word.ListTemplate
    
    Set doc = ActiveDocument
    Set listTemp = Word.Application.ListGalleries(wdOutlineNumberGallery).ListTemplates(1)
    
    For i = 1 To 9
        numFormatStr = numFormatStr & ".%" & i
        If Left(numFormatStr, 1) = "." Then
            numFormatStr = Mid(numFormatStr, 2)
        End If
        
        With listTemp.ListLevels(i)
            .NumberFormat = numFormatStr
            .TrailingCharacter = Word.WdTrailingCharacter.wdTrailingSpace
            .NumberStyle = Word.WdListNumberStyle.wdListNumberStyleArabic
            .NumberPosition = CentimetersToPoints(0)
            .Alignment = Word.WdListLevelAlignment.wdListLevelAlignLeft
            .TextPosition = CentimetersToPoints(0)
            .ResetOnHigher = i - 1
            .StartAt = 1
            .LinkedStyle = "标题 " & i
            With .Font
                .name = doc.Styles("标题 " & i).Font.name
                .NameFarEast = doc.Styles("标题 " & i).Font.NameFarEast
                .Size = doc.Styles("标题 " & i).Font.Size
                .Bold = doc.Styles("标题 " & i).Font.Bold
                .Italic = doc.Styles("标题 " & i).Font.Italic
            End With
        End With
    Next
    
    For Each pa In Selection.Paragraphs
        If pa.Style.NameLocal Like "标题 #" Then
            pa.Range.ListFormat.ApplyListTemplateWithLevel _
                ListTemplate:=listTemp, _
                ContinuePreviousList:=True, _
                ApplyTo:=wdListApplyToWholeList, _
                DefaultListBehavior:=wdWord10ListBehavior
        End If
    Next
    
    Set doc = Nothing
    Set listTemp = Nothing
End Sub
