jrxml报表，空白行问题。

Question

新人刚学jrxml，在做表格时遇到空白行将表格一分为二的情况。

表格的代码是：

 <band height="32">
            <staticText>
                <reportElement x="1" y="0" width="830" height="28" forecolor="#800000"/>
                <textElement textAlignment="Left" verticalAlignment="Middle">
                    <font fontName="宋体" size="14" isBold="true" isItalic="false" isUnderline="false"/>
                    <paragraph lineSpacingSize="2.0"/>
                </textElement>
                <text><![CDATA[审批历史记录]]></text>
            </staticText>
            <line>
                <reportElement x="1" y="30" width="830" height="1" forecolor="#C0C0C0"/>
            </line>
        </band>
        <band height="90">
            <componentElement>
                <reportElement x="1" y="1" width="530" height="1"/>
