使用 ireport 表组件时，我遇到了一个可能很简单的问题。我使用 XML 作为报告的数据源。

问题是该表从不显示与其关联的数据集的第一个条目。想象一下我有这些数据：

<name>
   <first>adam 1</first>
   <last>sand 1</last>          
</name> 
<name>
   <first>adam 2</first>
   <last>sand 2</last>          
</name> 
<name>
   <first>adam 3</first>
   <last>sand 3</last>          
</name>

输出（表）将是（除第一行之外的所有数据）：

第一个 最后
亚当 2 沙 2
亚当 3 沙 3

表中缺少数据源的第一行。

我认为这是与主数据源上的迭代有关的问题。您可以阅读
为什么我的子报表中缺少第一条记录？在community.jaspersoft.com上发帖。
