Question

我有一个类别和客户表，如下图所示：

enter image description here

然后我想从这些表中进行报告，并在jasper中按category id进行分组。这是我的jrxml文件：

    <?xml version="1.0" encoding="UTF-8"?>

    </detail>
</jasperReport>

此文件的结果如下：

但我希望我有这样的结果：

enter image description here

我该怎么做？

Answer 1

您可以使用条件样式。定义这样的风格：

<style name="myStyle">
    <box>
        <pen lineWidth="0.25"/>
        <topPen lineWidth="0.25"/>
        <leftPen lineWidth="0.25"/>
        <bottomPen lineWidth="0.25"/>
        <rightPen lineWidth="0.25"/>
    </box>
    <conditionalStyle>
        <conditionExpression><![CDATA[($F{CID} % 2) != 0]]></conditionExpression>
        <style mode="Opaque" forecolor="#000000" backcolor="#FFFF00"/>
    </conditionalStyle>
    <conditionalStyle>
        <conditionExpression><![CDATA[($F{CID} % 2) == 0]]></conditionExpression>
        <style forecolor="#000000" backcolor="#FFFFFF"/>
    </conditionalStyle>
</style>

将详细信息中的所有字段放入框架中，并将此样式设置为框架。

这在iReportUltimateGuide的“使用样式”部分

中进行了描述
