Jasper表组件 [英] Jasper table component

问题描述

我正在尝试生成包含表格的报告。这些是jrxml的重要部分：

I am trying to generate a report containing a table. These are the important parts from the jrxml:

<jasperReport
    <subDataset name="Table Dataset 1">
        <field name="field1" class="java.lang.String"/>
    </subDataset>
    <summary>
        <jr:table>
           <datasetRun subDataset="Table Dataset 1">
           <dataSourceExpression>
                        <![CDATA[$P{REPORT_DATA_SOURCE}]]>
                </dataSourceExpression>   
           </datasetRun>
           <jr:column width="90">
              <jr:columnHeader>...</jr:columnHeader>
              <jr:detailCell height="20">
              <textField>
                 <textFieldExpression class="java.lang.String">
                            <![CDATA[$F{territory}]]>
                         </textFieldExpression>
              </textField>
           </jr:detailCell>
           </jr:column>
        <jr:table>
    </summary>
</jasperReport>

我传递给报告的数据源类型是JRBeanArrayDataSource，看起来没问题，因为数据显示在报告中（如果我在主表中使用$ F {field1} - 在表格外）。

The type of datasource I am passing to the report is a JRBeanArrayDataSource, which seems to be ok, because the data appears in the report (if I am using $F{field1} in the master - outside the table).

你看到我的方式有问题吗？使用表组件？
我没有看到任何错误......但表格没有显示...只有一条水平线而不是表格。

Do you see something wrong in the way I am using the table component? I don't see any errors...but the table is not being displayed...only a horizontal line instead of the table.

I had the same problem and found the solution here https://web.archive.org/web/20111130110022/http://thilosdevblog.wordpress.com/2011/03/27/beans-in-jasperreports4/

表数据源必须如下所示：

the table datasource has to be like this:

<datasetRun subDataset="TableDataset">
    <datasetParameter name="REPORT_DATA_SOURCE">
       <datasetParameterExpression><![CDATA[$P{REPORT_DATA_SOURCE}]]></datasetParameterExpression>
    </datasetParameter>
</datasetRun>

想知道为什么这种东西不在jasper / ireport常见问题中！

Wonder why this kind how stuff is not in the jasper/ireport FAQ !
