Css 如何设置h:panelGrid中一行的高度

我想在h:panelGrid中设置一行的高度

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

我怎样才能做到这一点

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

以下是我的css类：

.height8 {
    height: 8px;
}

.height0 tr td{
    height: 0%
}

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

页面代码：

<h:panelGrid columns="2" columnClasses="height8, height8" rowClasses="height8">
    <h:outputText value="This row"/>
    <h:outputText value=" is ok"/>

    <h:outputText value="This row"/>
    <h:outputText value=" is ok"/>

    <h:outputText value="This row" styleClass="height0"/>
    <h:outputText value=" height should be different" styleClass="height0"/>

    <h:outputText value="This row"/>
    <h:outputText value=" is ok"/>
</h:panelGrid>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

样式类高度0在这里似乎不起作用。如何设置h:panelGrid中特定行的高度

更改以下样式类应该有效

.height0 tr td{
    height: 0px; //or what ever height you want to set to this row.
}

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

你有两条路：

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

内联样式：

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" style="height: 25px"/>
<h:outputText value=" is ok" style="height: 25px"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>

<h:outputText value="This row" id="customheight"/>
<h:outputText value=" is ok" id="customheight"/>

<h:outputText value="This row"/>
<h:outputText value=" is ok"/>
