jasper-reports - 如何从参数创建包含静态和动态值的表？

要使用jr:table组件，您需要有一个数据源，通常List您应该从一些后端代码中获取数据，例如将其作为参数传递给报表。因此，不是传递单个参数，而是传递具有名称和值的数据源。

然而，为了好玩？我们也可以在 jrxml 代码中创建一个数据源，例如在你的情况下我会使用ListOfArrayDataSource(java.util.List<java.lang.Object[]> records, java.lang.String[] columnNames)

创建前两个条目的代码将是这样的。

new net.sf.jasperreports.engine.data.ListOfArrayDataSource(
   Arrays.asList(
      new String[]{"Name", $P{name}}, 
      new String[]{"Date of Birth", $P{dateOfBirth}}
      ),
   new String[]{"c1", "c2"}
)
