Let's create a report representing pilots in a table. The table will have 2 fields: "Name" and "Points". The fields should be defined like this:
<field name="Name"
class="java.lang.String"/>
<field name="Points"
class="java.lang.Integer"/>
The field values - $F{Name} and $F{Points} - can be used in the table part of the report:
<detail>
<band height="15">
<textField bookmarkLevel="2">
<reportElement x="150" y="0"
width="175" height="15"/>
<box leftBorder="Thin" bottomBorder="Thin"
leftPadding="10" rightPadding="10"/>
<textElement textAlignment="Left"/>
<textFieldExpression
class="java.lang.String">$F{Name}</textFieldExpression>
<anchorNameExpression>$F{Name} + " (" + $F{Points} +
")"</anchorNameExpression>
</textField>
<textField isStretchWithOverflow="true">
<reportElement positionType="Float" x="325"
y="0" width="50" height="15"/>
<box leftBorder="Thin" bottomBorder="Thin"
rightBorder="Thin" leftPadding="10"
rightPadding="10"/>
<textElement textAlignment="Right"/>
<textFieldExpression
class="java.lang.Integer">$F{Points}</textFieldExpression>
</textField>
</band>
</detail>
