C# 在一个轴列中添加两个子列

我提到了下面的代码，它根据分配的任务为我提供了数据透视表。我想拆分数据透视标题，子列为开始日期和结束日期。如何在透视列中添加子列

你是说像交叉表报告这样的标题吗？我已经做了交叉表。。。。但现在我需要的是在pivot表的这列下面，我需要子列。。。这意味着每个任务下面都有两列，分别是开始日期和结束日期。我可以获得每个日期都有一个日期的任务如何在其下再显示两列在SQL SERVER中无法在一列下显示列。为此，您需要使用SSRS或其他一些报告服务。一种方法是显示Taks1StartDate、Task1EndDate、Taks2StartDate、Task2EndDate等列。这样就足够了吗@user2583182@SarathAvanavu：我不介意显示Taks1StartDate、Task1EndDate、Taks2StartDate、Task2EndDate等，但我如何使用Pivot显示它可以显示它。在此之前，我需要澄清。你需要静态轴心还是动态轴心@用户2583182
