这很容易。您应该为Table组件添加新的数据源,然后在该组件中使用它(数据源)。
示例jrxml:
<?xml version="1.0" encoding="UTF-8"?>
<jasperReport ... whenNoDataType="AllSectionsNoDetail" ...>
<style name="table">
<box>
<pen lineWidth="1.0" lineColor="#000000"/>
</box>
</style>
<style name="table_TH" mode="Opaque" backcolor="#F0F8FF">
<box>
<pen lineWidth="0.5" lineColor="#000000"/>
</box>
</style>
<style name="table_CH" mode="Opaque" backcolor="#BFE1FF">
<box>
<pen lineWidth="0.5" lineColor="#000000"/>
</box>
</style>
<style name="table_TD" mode="Opaque" backcolor="#FFFFFF">
<box>
<pen lineWidth="0.5" lineColor="#000000"/>
</box>
</style>
<subDataset name="tableDataset">
<queryString language="SQL">
<![CDATA[SELECT id, city, street FROM address ORDER BY city]]>
</queryString>
<field name="ID" class="java.lang.Integer"/>
<field name="CITY" class="java.lang.String"/>
<field name="STREET" class="java.lang.String"/>
<group name="CITY">
<groupExpression><![CDATA[$F{CITY}]]></groupExpression>
</group>
</subDataset>
<title>
<band height="58" splitType="Stretch">
<componentElement>
<reportElement key="table" style="table" x="0" y="0" width="299" height="46"/>
<jr:table xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd">
<datasetRun subDataset="tableDataset">
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
</datasetRun>
<jr:column width="90">
<jr:groupHeader groupName="CITY">
<jr:cell height="30" rowSpan="1">
<textField>
<reportElement x="0" y="0" width="90" height="30"/>
<textElement/>
<textFieldExpression><![CDATA[$F{CITY}]]></textFieldExpression>
</textField>
</jr:cell>
</jr:groupHeader>
<jr:columnHeader style="table_CH" height="30" rowSpan="1">
<staticText>
<reportElement x="0" y="0" width="90" height="30"/>
<textElement/>
<text><![CDATA[Id]]></text>
</staticText>
</jr:columnHeader>
<jr:detailCell style="table_TD" height="20" rowSpan="1">
<textField>
<reportElement x="0" y="0" width="90" height="20"/>
<textElement/>
<textFieldExpression><![CDATA[$F{ID}]]></textFieldExpression>
</textField>
</jr:detailCell>
</jr:column>
<jr:column width="90">
<jr:columnHeader style="table_CH" height="30" rowSpan="1">
<staticText>
<reportElement x="0" y="0" width="90" height="30"/>
<textElement/>
<text><![CDATA[Street]]></text>
</staticText>
</jr:columnHeader>
<jr:detailCell style="table_TD" height="20" rowSpan="1">
<textField>
<reportElement x="0" y="0" width="90" height="20"/>
<textElement/>
<textFieldExpression><![CDATA[$F{STREET}]]></textFieldExpression>
</textField>
</jr:detailCell>
</jr:column>
</jr:table>
</componentElement>
</band>
</title>
</jasperReport>
iReport中的设计如下所示:
- 主要报告视图:
- 表格组件视图:
在此示例中,我删除了主要数据源并将Table组件放入Title带。我设置了 whenNoDataType="AllSectionsNoDetail"属性来显示报告。
报告中的数据按城市字段分组。
