I've created a report with table (jr:table), but when I am trying to export it as excel, pagination is not ignored(table headers are repeated, and table content breaks). I've added isIgnorePagination="true", but it doesn't help. How does ignore pagination for table content?
A possible workaround for this is to put a Print When Expression of
$V{PAGE_NUMBER} == 1
to the Row Properties of your Column Header.
<jr:columnHeader>
<printWhenExpression><![CDATA[$V{PAGE_NUMBER} == 1]]></printWhenExpression>
</jr:columnHeader>
Adding these properties to the report itself should take care of the rest:
<property name="net.sf.jasperreports.export.xls.remove.empty.space.between.columns" value="true"/>
<property name="net.sf.jasperreports.export.xls.remove.empty.space.between.rows" value="true"/>
<property name="net.sf.jasperreports.export.xls.white.page.background" value="false"/>
And here is a working example:
