使用JavaScript通过C++在复制行或范围时将图表的数据源更改为目标工作表

可能的使用场景
当你将包含图表的行或区域复制到新工作表时，图表的数据源不会变化。例如，如果图表的数据源是 =Sheet1!$A$1:$B$4，那么在复制到新工作表后，数据源仍然是相同的，即=Sheet1!$A$1:$B$4，仍指向旧工作表（即Sheet1）。这也是Microsoft Excel中的行为。但如果你希望它指向新的目标工作表，请在调用Cells.copyRows(Cells, number, number, number)方法时使用CopyOptions.referToDestinationSheet属性并设置为true。假设目标工作表为DestSheet，则你的图表数据源将从=Sheet1!$A$1:$B$4变为=DestSheet!$A$1:$B$4。
复制行或区域时更改图表的数据源到目标工作表
以下示例代码解释了在复制包含图表的行或区域到新工作表时使用CopyOptions.referToDestinationSheet属性的方法。代码使用示例Excel文件（5113699.xlsx），并生成输出Excel文件（5113697.xlsx）。
