将Excel数据导出到Java中的单词表
#api #java #excel #word

当您需要根据Excel工作表中的数据中创建Word文档中的表时，通常可以通过复制和粘贴来完成任务。但是在此过程中，表格的格式可能会丢失，然后您需要在Word文档中重新格式化。本文将分享如何以编程方式将Excel数据转换为单词表并保留其格式在Java 应用中。

安装免费的尖峰。

要将Excel数据转换为Java中的单词表，您需要安装 free spire.office for Java 库。该图书馆完全免费用于商业和个人用途。以下是安装它的两种方法。
方法1：下载free library并解压缩，然后将spire.office.jar文件添加到您的项目中。

方法2：通过将以下配置添加到pom.xml。

示例代码

要将excel日期转换为单词表，您需要使用 cellrange.getValue（）方法来获取特定的Excel单元格的值 tablecell.addparagraph（）。appendText（）方法。为了保留表格格式，您可以使用自定义方法 copystyle（）将字体样式和单元格样式从excel复制到单词表。完整的示例代码如下所示。
