How to remove extra space between text field in JasperReports?

Question

I created three text fields in the header. I put the parameter in all the elements textField. When I do not call one of three parameters from three elements textField. It will display 2 textFielditems. The problem is that there is a space between the text fields.

How to remove a space?

This is my code:

<textField isBlankWhenNull="true">
    <reportElement x="0" y="18" width="555" height="35" isRemoveLineWhenBlank="true"/>
    <textElement textAlignment="Center">
        <font size="12"/>
    </textElement>
    <textFieldExpression><![CDATA[$P{daterangefrom}  && $P{daterangeto}  ?  "From ( " + $P{daterangefrom} + " - " + $P{daterangeto} + ")"
: $P{weeks}  && $P{monthy} && $P{yrs} ? "For week " + $P{weeks} +" "+ $P{monthy} +" "+ $P{yrs}
: $P{monthy}  && $P{yrs} ? "For monthly " +$P{monthy} +" "+ $P{yrs}
: $P{quarter}  &&  $P{yrs}  ? "For Quarter " + $P{quarter} +" "+$P{yrs}
: $P{yrs}  ? "For " + $P{yrs}
: null]]>
    </textFieldExpression>
</textField>

This is my result:

You can use 3 textFieldelements with the property set to value . isRemoveLineWhenBlanktrue

For parameter1 = null, parameter2 = null, parameter1 = value3, the result will be:
