原Excel文档：
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
public class WrapOrUnwrapText {
public static void main(String []args) throws Exception {
//创建Workbook实例

//加载Excel文档
workbook.loadFromFile("Input.xlsx");
//获取第一张工作表
Worksheet sheet = workbook.getWorksheets().get(0);
//设置单元格"A1"的文字自动换行
sheet.getRange().get("A1").getStyle().setWrapText(true);
//取消单元格"A6"的文字自动换行
sheet.getRange().get("A6").getStyle().setWrapText(false);
//保存文档
workbook.saveToFile("WrapOrUnwrapText.xlsx", ExcelVersion.Version2013);
}

当我们与同事协同编辑一份 Excel 文档时，常会遇到这样一种情况：若 Excel 文档数据存在问题，我们就需要对文档中各个部分或某些内容进行修改。通常我们就会用到修订功能。因为使用修订可以直观地跟踪到文档的修改情况，看出是哪位作者对文档进行了修改，以及修改的正确内容。如果对文档拥有完全权限，则可以接受或拒绝每个修订。在本文中，您将学习如何使用 Spire.XLS for Java 一次接受或拒绝所有修订。
首先，您需要在 Java 程序中添加 Spire.Xls.jar 文件作为依赖项。您可以从此链接下载 JAR 文件；如果您使用 Maven，则可以通过在 pom.xml 文件中添加以下代码导入 JAR 文件。
<repositories>
<repository>
<id>com.e-iceblue</id>
<name>e-iceblue</name>
<url>https://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.xls</artifactId>
<version>16.9.2</version>
</dependency>
</dependencies>
您可以使用 Workbook.hasTrackedChanegs() 方法来确定工作簿是否已修订。如果是，可以使用 Workbook.acceptAllTrackedchanges() 方法一次接受所有修订。以下是在 Excel 工作簿中接受修订的具体步骤：
import com.spire.xls.FileFormat;
import com.spire.xls.Workbook;
public class AcceptTrackedChanges {
public static void main(String[] args) {
//创建一个Workbook对象
Workbook wb = new Workbook();
//加载示例 Excel 文档
wb.loadFromFile("test.xlsx");
//确认工作簿是否已修订
if (wb.hasTrackedChanges())
{
//接受修订
wb.acceptAllTrackedChanges();
}
//保存文件
wb.saveToFile("AcceptChanges.xlsx", FileFormat.Version2013);
}
}
如果已确定修订存在于工作簿中，您可以使用 Workbook.rejectAllTrackedChanges() 方法拒绝工作表中的修订。以下是实现此目的的步骤:
import com.spire.xls.FileFormat;
import com.spire.xls.Workbook;
public class RejectTrackedChanges {
public static void main(String[] args) {
//创建一个Workbook对象
Workbook wb = new Workbook();
//加载示例 Excel 文档
wb.loadFromFile("test.xlsx");
//确认工作簿是否已修订
if (wb.hasTrackedChanges())
{
//拒绝修订
wb.rejectAllTrackedChanges();
}
//保存文件
wb.saveToFile("RejectChanges.xlsx", FileFormat.Version2013);
}
}

项目符号和编号是放在文本前的点或其它符号，起强调作用。合理使用项目符号和编号，可以使文档的层次结构更清晰、更有条理。通过组织良好的列表，读者可以轻松了解每个项目的结构和要点。 本文将介绍如何使用 Spire.Doc for Java 从 Word 文档中的现有文本创建列表。
首先，您需要在 Java 程序中添加 Spire.Doc.jar 文件作为依赖项。您可以从此链接下载 JAR 文件；如果您使用 Maven，则可以通过在 pom.xml 文件中添加以下代码导入 JAR 文件。
<repositories>
<repository>
<id>com.e-iceblue</id>

<artifactId>spire.doc</artifactId>
<version>14.9.5</version>
</dependency>
</dependencies>
Spire.Doc for Java 提供了 ListFormat.applyBulletStyle() 和 ListFormat.applyNumberedStyle() 两种方法，用于创建项目符号和编号列表。
创建项目符号和编号列表的详细步骤如下:
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.formatting.ListFormat;
public class CreateLists {
public static void main(String[] args) {
//创建 Document 类的对象
Document document = new Document();
//加载 Word 文档
document.loadFromFile("测试文档.docx");
//获取第一节
Section section = document.getSections().get(0);
//循环遍历第 4 到第 6 段
for(int i = 3; i <= 5; i++){
Paragraph para = section.getParagraphs().get(i);
ListFormat listFormat = para.getListFormat();
//应用项目符号列表样式
listFormat.applyBulletStyle();
//设置列表位置
listFormat.getCurrentListLevel().setNumberPosition(-10);
}
//循环遍历第 8 到第 10 段
for(int i = 7; i <= 9; i++){
Paragraph para = section.getParagraphs().get(i);
ListFormat listFormat = para.getListFormat();
//应用编号列表样式
listFormat.applyNumberedStyle();
//设置列表位置
listFormat.getCurrentListLevel().setNumberPosition(-10);
}
//保存文件
document.saveToFile("创建列表.docx", FileFormat.Docx_2013);
}
}
