Jasper table component
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">
<dataSourceExpre开发者_如何学运维ssion>
<![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>
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 $F{field1} in the master - outside the table).
Do you see something wrong in the way I am using the table component? I don't see any errors...but the table is not being displayed...only a horizontal line instead of the table.
I had the same problem and found the solution here https://web.archive.org/web/20111130110022/http://thilosdevblog.wordpress.com/2011/03/27/beans-in-jasperreports4/
the table datasource has to be like this:
<datasetRun subDataset="TableDataset">
<datasetParameter name="REPORT_DATA_SOURCE">
<datasetParameterExpression><![CDATA[$P{REPORT_DATA_SOURCE}]]></datasetParameterExpression>
</datasetParameter>
</datasetRun>
Wonder why this kind how stuff is not in the jasper/ireport FAQ !
Well, I can't comment and can't vote up but I have tested and can confirm that @Flo's answer works all right.
Edit: the first row is missing. See how to fix it: Jasper report missing first row and JasperReports Tutorial: Missing Record Bug
