本文介绍如何使用Spire.Doc for Java在Word文档中添加上角标和下角标。

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.BreakType;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.SubSuperScript;
import com.spire.doc.fields.TextRange;

public class InsertSupSubScript {

    public static void main(String[] args) {

        //创建Document对象
        Document document = new Document();

        //添加节
        Section section = document.addSection();

        //添加段落
        Paragraph paragraph = section.addParagraph();

        //添加文字到段落
        paragraph.appendText("E = mc");

        //添加文字并设置为上角标
        TextRange textRange = paragraph.appendText("2");
        textRange.getCharacterFormat().setSubSuperScript(SubSuperScript.Super_Script);

        //添加换行
        paragraph.appendBreak(BreakType.Line_Break);

        //添加文字并设置部分文字为下角标
        paragraph.appendText("a");
        paragraph.appendText("n").getCharacterFormat().setSubSuperScript(SubSuperScript.Sub_Script);
        paragraph.appendText(" = S");
        paragraph.appendText("n").getCharacterFormat().setSubSuperScript(SubSuperScript.Sub_Script);
        paragraph.appendText(" - S");
        paragraph.appendText("n-1").getCharacterFormat().setSubSuperScript(SubSuperScript.Sub_Script);

        //保存文档
        document.saveToFile("InsertSubSuperScript.docx", FileFormat.Docx);
    }
