Tip : Row banding and column banding OR alternative colors for rows and columns in Jaspersoft Studio 6.x in cross tab component

Hi Folks,

Usually we write grid reports by making use of column header and Detail band or table component in JRXML file. 

When write a grid report using column headers, we make use of Styles and conditional expression with REPORT_COUNT variable to get the alternative colors, similarly when we use Table component, we take check box utility in its style section to get the alternative colors functionally.

Today, I need to implement the row or column banding in cross tab component - cross tab also mean to display grid data but the data will be grouped by rows and columns. Neither we can't use  REPORT_COUNT variable on cross tab fields nor any utility.

Here are the steps to have row or column banding.

1) Write your cross tabular report.
2) Go to Style section from report outline or cross tab outline.
3) Create a Style -> Create two conditional Styles. One for row banding another for column banding.
    Lets say Style name is Style1
4) Write below condition in 1st condition & on its Appearance section choose row banding color.
    $V{ROW_COUNT}%2==0
5) Write below condition in 2nd condition of same Style1& on its Appearance section choose another color for column
   $V{COLUMN_COUNT}%2==0
6) Now , go the cross tabs text elements and select them and apply Style1 in Appearance section for Style property.
7) Save your report and preview.

NOTE : 
1) While choosing colors on condition do not uncheck "Transperant" property.
2) On cross tab text fields you must uncheck "Transparent" property.
3)  COLUMN_COUNT and ROW_COUNT are built in variables that you can see in grayed out color in Variables section.
4) ROW_COUNT is not available by default in variables section in 6.2 studio.

Sample output : 
1) Cross tab row banding
 
2) Cross tab row banding + Column banding


Style code in JRXML : 
    <style name="Style1">
        <conditionalStyle>
            <conditionExpression><![CDATA[$V{ROW_COUNT}%2==0]]></conditionExpression>
            <style backcolor="#C6EDF7"/>
        </conditionalStyle>
        <conditionalStyle>
            <conditionExpression><![CDATA[$V{COLUMN_COUNT}%2==0]]></conditionExpression>
            <style backcolor="#DBB2D3"/>
        </conditionalStyle>
    </style>


Applying Row banding code sample on a text field
<textField>
   <reportElement style="Style1" mode="Opaque" x="0" y="0" width="60" height="20" uuid="2dd638c2-fd6a-4bbf-8fb9-f9807dc1ee97"/>
   <textElement textAlignment="Left" verticalAlignment="Middle"/>
   <textFieldExpression><![CDATA[$V{education1}]]></textFieldExpression>
     </textField>
