Print when last row on table Jasper report

问题

I have a report that needs to have an image printed only in the last row of the table of each page. How can I create my print when expression?

Edit:

Sorry for my poor exemple.

until now, i created this variable

<variable name="rowsOnPage" class="java.lang.Integer">
        <variableExpression><![CDATA[$V{rowsOnPage} + 1]]></variableExpression>
        <initialValueExpression><![CDATA[0]]></initialValueExpression>
</variable>

and i try this print when expression:

$V{rowsOnPage} == $V{REPORT_COUNT}

But this expression print the image in each row of table.

As Petter says, providing an example of what you've tried and how close you've got so far would be helpful.

In the meantime my suggestion is that you add a max rowcount value to your SQL and return this as field in your JRXML as e.g. maxRowNum. With this you could then use a printWhen at the point when $V{REPORT_COUNT} == $F{maxRowNum}

This assumes you have access to the SQL part of your code and can play with this.
