vba - 从 Word 文档中删除前导空格

Question

如何从 Word 文档的第一页中删除所有前导空格（空格、空行）？

Answer 1

编辑：原来我想要的是从文档的开头删除所有空段落或仅包含空格的段落。以下宏DeleteLeadingWhitespace执行此操作并保留格式。

' return True if the character at the given position is a whitespace character.

Function IsSpace(ByVal Text As String, Optional ByVal Position As Long = 1)

    Select Case AscW(Mid(Text, Position, 1))
        Case &H9, &HA, &HB, &HC, &HD, &H20, &H85, &HA0, _
                &H1680, &H180E, &H2000, &H2001, &H2002, &H2003, &H2004, &H2005, &H2006, _
                &H2007, &H2008, &H2009, &H200A, &H2028, &H2029, &H202F, &H205F, &H3000
            IsSpace = True

        Case Else
            IsSpace = False
    End Select

End Function

' return True if the paragraph consists only of whitespace
Function IsParagraphEmpty(ByVal pg As Paragraph)

    Dim i As Long

    For i = 1 To Len(pg.Range.Text)
        If Not IsSpace(pg.Range.Text, i) Then
            IsParagraphEmpty = False
            Exit Function
        End If
    Next

    IsParagraphEmpty = True
End Function

' delete leading whitespace from the given document.
Sub DeleteLeadingWhitespaceFrom(ByVal Document As Document)

    While IsParagraphEmpty(Document.Paragraphs.First)
        Dim i As Long
        i = Document.Paragraphs.Count

        Document.Paragraphs.First.Range.Delete

        ' no change in number of paragraphs, bail
        If i = Document.Paragraphs.Count Then Exit Sub

    Wend

End Sub

' macro: delete leading whitespace from the active document
Sub DeleteLeadingWhitespace()

    DeleteLeadingWhitespaceFrom ActiveDocument

End Sub
