如何在两列中创建列表控件jr：list？

Question

我有一个碧玉的报告列表控件，可以从后端获取动态值。我需要在两列中显示列表值。

我该怎么做？

这是我的jr:list

代码

<jr:list xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" printOrder="Horizontal">
    <datasetRun subDataset="accessorialsDataset" uuid="b0e600e0-5797-42b4-8078-12dd4231dd3d">
        <dataSourceExpression><![CDATA[$P{accessorialDataSource}]]></dataSourceExpression>
    </datasetRun>
    <jr:listContents height="12" width="524">
        <textField isStretchWithOverflow="true" isBlankWhenNull="true">
            <reportElement positionType="Float" x="0" y="0" width="259" height="12" uuid="221d3ff4-39a7-4ddd-bc74-50bed600819b"/>
            <textElement>
                <font fontName="Liberation Sans" size="8"/>
            </textElement>
            <textFieldExpression><![CDATA[$F{accessorial}]]></textFieldExpression>
        </textField>
    </jr:listContents>
</jr:list>

Answer 1

要在jr:list组件集printOrder="Horizontal"上实现多列，然后将jr:listContents的宽度指定为您需要对包含{{ 1}}

包含2列的示例

jr:list
