节

Sections

中文

Word 支持 section(节) 的概念，具有不同的页面布局设置。例如，一个文档可以包含纵向布局的某些页面和横向布局的另一些页面。分节符的实现方式与换行符、分页符和分栏符完全不同。前者在新节的最后一段中添加一个 <w:pPr><w:sectPr> 元素。后者在运行中插入一个 <w:br> 元素。

文档中的最后一节由 <w:sectPr> 元素指定，该元素是 <w:body> 元素的最后一个子元素。虽然此元素是可选的，但 Word 似乎为所有文件创建了它。由于大多数文件只有一个节，最常见的情况是这是唯一的 <w:sectPr> 元素。

其他节由节最后一段中的 w:p/w:pPr/w:sectPr 元素指定。该段落中的任何内容都是由其 <w:sectPr> 元素定义的部分的一部分。后续部分以下段落开始。

使用 Word UI 插入分节符时，将发生以下步骤：

1. 复制下一个出现的 <w:sectPr> 元素并将其添加到当前段落。（如果该段落已经有一个 <w:sectPr> 元素，看看会发生什么会很有趣。）

2. 在当前段落后插入一个新段落。光标位置后的文本将移动到新段落。

3. 下一个出现的 <w:sectPr> 元素的起始类型（例如下一页）将更改为反映用户从 UI 中选择的类型。

英文

Word supports the notion of a section, having distinct page layout settings. This is how, for example, a document can contain some pages in portrait layout and others in landscape. Section breaks are implemented completely differently from line, page, and column breaks. The former adds a <w:pPr><w:sectPr> element to the last paragraph in the new section. The latter inserts a <w:br> element in a run.

The last section in a document is specified by a <w:sectPr> element appearing as the last child of the <w:body> element. While this element is optional, it appears that Word creates it for all files. Since most files have only a single section, the most common case is where this is the only <w:sectPr> element.

Additional sections are specified by a w:p/w:pPr/w:sectPr element in the last paragraph of the section. Any content in that paragraph is part of the section defined by its <w:sectPr> element. The subsequent section begins with the following paragraph.

When a section break is inserted using the Word UI, the following steps occur:

1. The next-occurring <w:sectPr> element is copied and added to the current paragraph. (It would be interesting to see what happens when that paragraph already has a <w:sectPr> element.)

2. A new paragraph is inserted after the current paragraph. The text occuring after the cursor position is moved to the new paragraph.

3. The start-type (e.g. next page) of the next-occuring <w:sectPr> element is changed to reflect the type chosen by the user from the UI.

Word 行为

Word behavior

中文

• 包含分节符（<w:sectPr> 元素）的段落不会在 Word UI 中产生 ¶ 字形。

• 分节符指示符/双线直接出现在出现 <w:sectPr> 的段落文本之后。如果分节符段落没有文本，指示线将立即出现在前一个段落的段落标记之后。

英文

• A paragraph containing a section break (<w:sectPr> element) does not produce a ¶ glyph in the Word UI.

• The section break indicator/double-line appears directly after the text of the paragraph in which the <w:sectPr> appears. If the section break paragraph has no text, the indicator line appears immediately after the paragraph mark of the prior paragraph.

包含两个段落的基线文件:

<w:body>
  <w:p>
    <w:r>
      <w:t>Paragraph 1</w:t>
    </w:r>
  </w:p>
  <w:p>
    <w:r>
      <w:t>Paragraph 2</w:t>
    </w:r>
  </w:p>
  <w:sectPr>
    <w:pgSz w:w="12240" w:h="15840"/>
    <w:pgMar w:top="1440" w:right="1800" w:bottom="1440" w:left="1800"
            w:header="720" w:footer="720" w:gutter="0"/>
    <w:cols w:space="720"/>
    <w:docGrid w:linePitch="360"/>
  </w:sectPr>
</w:body>

奇数页部分插入第 1 段的段落标记之前:

<w:body>
  <w:p>
    <w:pPr>
      <w:sectPr>
        <w:pgSz w:w="12240" w:h="15840"/>
        <w:pgMar w:top="1440" w:right="1800" w:bottom="1440" w:left="1800"
                w:header="720" w:footer="720" w:gutter="0"/>
        <w:cols w:space="720"/>
        <w:docGrid w:linePitch="360"/>
      </w:sectPr>
    </w:pPr>
    <w:r>
      <w:t>Paragraph 1</w:t>
    </w:r>
  </w:p>
  <w:p/>
  <w:p>
    <w:r>
      <w:t>Paragraph 2</w:t>
    </w:r>
  </w:p>
  <w:sectPr w:rsidR="00F039D0" w:rsidSect="006006E7">
    <w:type w:val="oddPage"/>
    <w:pgSz w:w="12240" w:h="15840"/>
    <w:pgMar w:top="1440" w:right="1800" w:bottom="1440" w:left="1800"
            w:header="720" w:footer="720" w:gutter="0"/>
    <w:cols w:space="720"/>
    <w:docGrid w:linePitch="360"/>
  </w:sectPr>
</w:body>

UI 在新的下一页的第一个位置显示空的 ¶ 标记。分节符指示符直接出现在第 1 段文本之后，中间没有 ¶ 标记。

在第 2 段的第一个字符前插入偶数页分节符:

<w:body>
  <w:p>
    <w:r>
      <w:t>Paragraph 1</w:t>
    </w:r>
  </w:p>

    <w:docGrid w:linePitch="360"/>
  </w:sectPr>
</w:body>
