LESSON: Why Excel Cell Exported From Jasper Server Has No Grid Displayed

1. Problem Description

Environment: Jasper Studio 5.6.2 community edition., Jasper Server 5.6.2 community edition (minimal installation).

Excel exporter setting:

<bean id="xlsExportParameters" class="com.jaspersoft.jasperserver.api.engine.jasperreports.common.XlsExportParametersBean">
        <property name="detectCellType" value="true"/>
        <property name="onePagePerSheet" value="true"/>
        <property name="removeEmptySpaceBetweenRows" value="false"/>
        <property name="removeEmptySpaceBetweenColumns" value="false"/>
        <property name="whitePageBackground" value="true"/>
        <property name="ignoreGraphics" value="false"/>
        <property name="collapseRowSpan" value="true"/>
        <property name="ignoreCellBorder" value="false"/>
        <property name="fontSizeFixEnabled" value="true"/>
        <property name="maximumRowsPerSheet" value="0"/>
        <property name="xlsFormatPatternsMap" ref="formatPatternsMap"/>
    </bean>

During jasper report development, I met an annoying problem, there is no grid in the exported excel, and the excel looks really bad, shown as below,

2. Analysis and Solution

In short, we should set all table styles as 'transparent'.
