I am using JasperReports 4.6.0 and JDK 1.6 to generate my .docx report.

Jasper generates actually the report by default in a form of a one column table, where every component (e.g. TextField) occupies one row. The problem I am facing in the present situation is that whenever I want to edit my output report and add manually a new line in some textField, I have to widen the height of the given textField by widening the table row (i.e. click and slide).

This seems to be a tedious task to do. So I had a look at the properties of a casual MS Word table and I have noticed a property called "Specify height"

]1

That is enabled by default in my jasper output report. If disabled, one could simple add a CR and all rows beneath would move as well. That being said, I want to disable this property in my jasper (whether from java or jrxml).

Here's my jrxml :

To disable “Specify Height” property, you should set property

net.sf.jasperreports.export.docx.flexible.row.height=true, default it is false

jrxml

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="report4" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="afeb1e80-f428-4ec0-930e-64d32f4d7e57">
    <property name="net.sf.jasperreports.export.docx.flexible.row.height" value="true"/>
....
</jasperReport>

IDE (JasperSoft Studio)

Select report in in outline, in properties switch to tab advanced, click the button that appear when you select the properties property

This opens a dialog, press "add", and insert the property
