This seems to work:

Sub ConvertListsInTableToNumbered()
Dim tbl As Table
Dim cell As cell
Dim para As Paragraph
  'Define the table we want to process
  Set tbl = ActiveDocument.Tables(1) ' Change the table index as needed
  'Loop through each cell in the table
  For Each cell In tbl.Range.Cells
    'Loop through each paragraph in the cell
    For Each para In cell.Range.Paragraphs
      para.Range.Select
      'Check if the paragraph has a numbered or bulleted list format
      If para.Range.ListFormat.ListType <> wdListNoNumbering Then
        'Convert the list to a numbered list
        para.Range.ListFormat.ApplyListTemplate ListTemplate:= _
        ListGalleries(wdNumberGallery).ListTemplates(2), _
        ContinuePreviousList:=False, ApplyTo:=wdListApplyToWholeList, _
        DefaultListBehavior:=wdWord10ListBehavior
        Exit For
      End If
    Next para
  Next cell
End Sub
