可能的使用场景
早期，Aspose.Cells为普通工作表创建了PdfBookmarkEntry。但现在，Aspose.Cells也可以为图表工作表创建PdfBookmarkEntry。由于图表工作表没有除A1单元格之外的其他单元格，它只会为A1单元格创建PdfBookmarkEntry。
为图表工作表创建PdfBookmarkEntry
以下示例代码加载了具有四个工作表的示例Excel文件，其中两个是普通工作表，另外两个是图表工作表。它创建了四个书签条目，如下所示
- 书签I
- 书签II-Chart1
- 书签III
- 书签IV-Chart2
以下屏幕截图显示了示例代码生成的输出PDF以供参考。
