How do I delete extra space between rows in Jasper reports?
•
Java
This is my JRXML Code:
<?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="example_report" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <field name="name" class="java.lang.String"/> <field name="test" class="java.lang.String"/> <field name="price" class="java.lang.Double"/> <background> <band splitType="Stretch"/> </background> <title> <band height="79" splitType="Stretch"/> </title> <pageHeader> <band height="35" splitType="Stretch"/> </pageHeader> <columnHeader> <band height="61" splitType="Stretch"/> </columnHeader> <detail> <band height="125" splitType="Stretch"> <textField> <reportElement stretchType="RelativeToBandHeight" x="0" y="0" width="209" height="20"/> <textElement/> <textFieldExpression class="java.lang.String"><![CDATA[$F{name}]]></textFieldExpression> </textField> <textField> <reportElement x="209" y="0" width="201" height="20"/> <textElement/> <textFieldExpression class="java.lang.String"><![CDATA[$F{test}]]></textFieldExpression> </textField> <textField> <reportElement x="410" y="0" width="145" height="20"/> <textElement/> <textFieldExpression class="java.lang.Double"><![CDATA[$F{price}]]></textFieldExpression> </textField> </band> </detail> <columnFooter> <band height="45" splitType="Stretch"/> </columnFooter> <pageFooter> <band height="54" splitType="Stretch"/> </pageFooter> <summary> <band height="42" splitType="Stretch"/> </summary> </jasperReport>
When I add data sets to compiled reports in my application, I gain additional space between rows How do I delete this extra space?
Solution
I think that's because you declared 125px for each line:
<detail> <band height="125" splitType="Stretch">
But only 20px is used:
<reportElement stretchType="RelativeToBandHeight" x="0" y="0" width="209" height="20"/>
Try setting the detail band to the height you use (20px):
<detail> <band height="20" splitType="Stretch">
I'm not sure because I haven't used Jasper for months, but try this
