嗨我正在尝试垂直对齐两个元素

代码是

<h:panelGrid columns="2">
        <a4j:outputPanel layout="block">
            <h:form>
                <h:inputText id="text1" label="text1" value="#{opBean1.text}">
                    <f:validateLength maximum="10" />
                    <a4j:ajax event="keyup" execute="@this" render="out1" onerror="return false;" />
                </h:inputText><br/>
                <h:outputText id="out1" rendered="#{not empty opBean1.text}" value="Approved Text: #{opBean1.text}" />
            </h:form>
        </a4j:outputPanel>

        <a4j:outputPanel layout="block">
            <h:form>
                <h:inputText id="text2" label="text2" value="#{opBean1.text2}">
                    <f:validateLength maximum="10" />
                    <a4j:ajax event="keyup" execute="@this" render="out2" onerror="return false;" />
                </h:inputText><br/>
                <h:outputText id="out2" rendered="#{not empty opBean1.text2}" value="Approved Text: #{opBean1.text2}" />
            </h:form>
        </a4j:outputPanel>
</h:panelGrid>

如您所见，其中<h:panelGrid>包含两列。每列都有一个<a4j:outputPanel>元素。

问题是罐子的垂直尺寸<a4j:outputPanel>会发生变化。（<h:outputText id="xxx" rendered="#{not empty opBean1.xxx}" value="Approved Text: #{opBean1.xxx}" />仅当托管 bean opBean1 中的 xxx 值不为空时，才会呈现该元素）

因此，如果我在第一个 a4j 面板中输入一些文本，它将垂直包含两行，而另一个 a4j 面板将只包含一个。因此，第二个面板的 inputText 字段将不再与第一个面板的文本字段对齐。

我知道如果没有任何图形表示，这可能很难理解，所以我会告诉你我的意思：在输入文本之前：

inputText1  inputText2

输入文字后：

inputText1
            inputText2
outputText1

我希望它是：

inputText1 inputText2

outputText1

编辑（对不起识别......我不知道如何让它变得更好）
