可能的使用场景
您可以使用C++的Aspose.Cells for JavaScript将单元格连接到XML映射元素。请使用Cells.linkToXmlMap(string, number, number, string)方法实现。
将单元格链接到 XML 地图元素
以下示例代码加载了包含 XML 地图的 源 Excel 文件，然后将单元格 A1、B2、C3、D4、E5 和 F6 链接到 XML 地图元素 FIELD1、FIELD2、FIELD4、FIELD5、FIELD7 和 FIELD8，然后将工作簿保存在 输出 Excel 文件 中。
如果您打开 输出 Excel 文件 并单击“开发人员 > 源”按钮，您将看到单元格已链接到 XML 地图元素，并且它们也将被 Microsoft Excel 标记，如下图所示。
