为 Java 安装 Spire.Doc

首先，您需要在 Java 程序中添加 Spire.Doc.jar 文件作为依赖项。

合并单元格时删除重复值

以下是删除 Word 表格中合并单元格中重复值的步骤。

• 创建Document类的对象并使用Document.loadFromFile()方法加载示例文档。
• 使用Document.getSections()方法获取节集合，然后使用SectionCollection.get()方法获取特定节。
• 使用Section.getTables()方法获取表集合，然后使用TableCollection.get()方法获取想要的表
• 调用mergeCell(Table table, boolean isHorizontalMerge, int index, int start, int end)方法来垂直或水平合并表格单元格。此方法会判断要合并的单元格是否具有相同的值，并且将在合并单元格中仅保留一个值。
• 使用Document.saveToFile()方法将文档保存到文件。
