场景：通过两次调用WorkBookDesigner.SetDataSource(DataSet)添加两个DataSet，每个DataSet都有一个客户的DataTable，DataTable有不同的名字。

6.0.1：工作正常

7.3.1：异常

测试方法 Nirvana.Reporting.Engines.Aspose.Tests.Cells.AsposeCellsEngineTests.Execute_Report_NoTemplate_TemplateTypeDesigner_FormatXLS_ReturnsEmptySpreadSheet 抛出异常：Nirvana.Reporting.Core.ReportExecutionException：执行报告“CustomerList”时发生错误---> System.ArgumentException：已添加项目。在字典中键入：'PHONENUMBERS' 正在添加的键：'PHONENUMBERS'

System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add)
System.Collections.Hashtable.Add(Object key, Object value)
Aspose.Cells.WorkbookDesigner.SetDataSource(DataTable dataTable)

这个问题看起来像一个回归，但它可能会在最新版本中得到解决。因此，您应该尝试最新版本：Aspose.Cells for .NET 8.4.2，看看它是否有任何不同。

注意：我在 Aspose 担任开发人员布道师
