Exact Row Heights

Another way to overcome the issue described in Spacing Factor section is to set exact row heights for table rows. This is controlled by the USE_EXACT_ROW_HEIGHTS parameter. By default, its value is true. This means that row heights are exactly equal to the designed values. However, you can also disable this option (set to false) in case you see something wrong with your report layout. You may also disable this option (set to false) if you need to edit your report manually and want row height to increase automatically when you type something inside a table cell.

In JasperReports:

Java

   import com.aspose.words.jasperreports.*;
   AWDocExporter exporter = new AWDocExporter();
   exporter.setParameter(AWExporterParameter.USE_EXACT_ROW_HEIGHTS, false);
   exporter.exportReport();

In JasperServer:

XML

<bean id="aw_exportParameters" class="com.aspose.words.jasperreports.AWExportParametersBean">
    <property name="useExactRowHeights" value="false"/>
</bean>
