如何在jr：table组件中预先定义的行数之后引入分页符？

时间：2017-05-29 06:25:58

标签： jasper-reports page-break

我正在使用jasper报告版本6.1，并希望在jr:table组件中预定义的行数之后分页。我也试过在第5版中做同样的事情并且它工作正常但在版本6+中我无法做到。

如果有任何人有其他解决方案，请分享我所遵循的链接，请告诉我。

这就是我的尝试：

在subasset中使用组表达式的解决方案在jasper report v6 +中也可以正常工作。

示例（根据此answer的代码和数据构建）

将groupExpression添加到subDataset以便每2条记录($V{REPORT_COUNT}-1)/2)

中断到新页面 
<subDataset name="tableDataset" uuid="7a53770f-0350-4a73-bfc1-48a5f6386594">
    <field name="User" class="java.lang.String"/>
    <field name="Rep" class="java.math.BigDecimal"/>
    <group name="pageBreakGroup" isStartNewPage="true">
        <groupExpression><![CDATA[(int)(($V{REPORT_COUNT}-1)/2)]]></groupExpression>
    </group>
</subDataset>
