Question

看起来，Word Open XML的ECMA规范没有指定如何使用vertAlign属性呈现“运行”。是否有描述预期行为的文件：

上标和下标使用什么字体大小？
将上标/下标文本相对于基线移动多少？

仅供参考，这里是MS Word为包含文本“X²”的简单文档生成的document.xml（为简洁起见，省略了XML名称空间）：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<w:document>
  <w:body>
    <w:p w14:paraId="4B8ED8F1" w14:textId="3891D3E1" 
         w:rsidR="00CE1223" w:rsidRDefault="00886D56">
      <w:r>
        <w:t>X</w:t>
      </w:r>
      <w:r w:rsidRPr="00886D56">
        <w:rPr>
          <w:vertAlign w:val="superscript"/>
        </w:rPr>
        <w:t>2</w:t>
      </w:r>
      <w:bookmarkStart w:id="0" w:name="_GoBack"/>

      <w:pgMar w:top="1440" w:right="1440" w:bottom="1440" w:left="1440" 
               w:header="720" w:footer="720" w:gutter="0"/>
      <w:cols w:space="720"/>

Answer 1

RunProperties元素具有以下两个子元素，可用于设置具有Run的VerticalTextAlignment的位置和字体：

RunFonts元素，可用于设置字体类型
Position元素可用于相对于其默认基线降低或提高运行次数。

使用这些元素，您可以创建一个上标并具有调整后的字体的运行：

// Add headers to describe file
let headers = {
   'Content-disposition': 'attachment; filename="' + 'giraffe.jpg' + '"',
   'Content-Type': 'image/png'
};

// Streams are supported for reading files.
let remoteReadStream = bucket.file('giraffe.jpg').createReadStream();

// Set the response code & headers and pipe content to response
res.status(200).set(headers);
remoteReadStream.pipe(res);

这将输出以下openxml：

    // Creates an RunProperties instance and adds its children.
    public RunProperties GenerateRunProperties()
    {
        RunProperties runProperties1 = new RunProperties();
        RunFonts runFonts1 = new RunFonts(){ Ascii = "Times New Roman", HighAnsi = "Times New Roman", ComplexScript = "Times New Roman" };
        FontSize fontSize1 = new FontSize(){ Val = "48" };
        VerticalTextAlignment verticalTextAlignment1 = new VerticalTextAlignment(){ Val = VerticalPositionValues.Superscript };

        runProperties1.Append(runFonts1);
        runProperties1.Append(fontSize1);
        runProperties1.Append(verticalTextAlignment1);
        return runProperties1;
    }

您可以使用以下元素移动垂直对齐的行程：

<w:rPr xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
   <w:rFonts w:ascii="Times New Roman" w:hAnsi="Times New Roman" w:cs="Times New Roman" />
  <w:sz w:val="48" />
  <w:vertAlign w:val="superscript" />
</w:rPr>

生成以下openXML：

    // Creates an RunProperties instance and adds its children.
    public RunProperties GenerateRunProperties()
    {
        RunProperties runProperties1 = new RunProperties();
        RunFonts runFonts1 = new RunFonts(){ Ascii = "Times New Roman", HighAnsi = "Times New Roman", ComplexScript = "Times New Roman" };
        Position position1 = new Position(){ Val = "-10" };
        FontSize fontSize1 = new FontSize(){ Val = "48" };
        VerticalTextAlignment verticalTextAlignment1 = new VerticalTextAlignment(){ Val = VerticalPositionValues.Superscript };

        runProperties1.Append(runFonts1);
        runProperties1.Append(position1);
        runProperties1.Append(fontSize1);
        runProperties1.Append(verticalTextAlignment1);
        return runProperties1;
    }

根据您分配给position元素的值，运行将相对于其基线升高或降低：

Positve =>已举起
负面=>降低
