Adjust the row height of a datatable in JSF 2.0

Question

Adjust the row height of a datatable in JSF 2.0

I'm struggling to change the row height of my JSF datatable. Here's what I have:

<h:dataTable value="#{myBean.myValue}"
             rowClasses="dt_row"
             var="o">


</h:dataTable>

I've defined a css class called dt_row with a height of 10px, but it doesn't seem to be applying correctly. The generated page source looks fine:

<tr class="dt_row">

Any suggestions on why the row height isn't changing as expected?

Here is the code for my entire table:

    <h:dataTable value="#{searchBean.searchResult.concordances}"
                 styleClass="table"
                 var="concordance">

        <h:column>
            <pre>#{concordance.left}</pre>
        </h:column>

        <h:column>
            <pre style="color: blue;">#{concordance.middle}</pre>
        </h:column>

        <h:column>
            <pre>#{concordance.right}</pre>
        </h:column>

    </h:dataTable>

When working with HTML, it's important to note that the tr element does not have a height attribute. Instead, the height can be defined for individual td elements.

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core">
    <h:head>
        <title>DataTable Row Height Sample</title>
        <style type="text/css">
            table {
                width: 200px;
            }
            table tr {
                color: darkorange;
            }
            table tr td {
                height: 80px;
            }
        </style>
    </h:head>
    <h:body>
        <h:form id="myForm">
            <h1>Show data</h1>
            <!-- check that I'm using styleClass, not rowClass -->
            <h:dataTable id="dataTable" var="data" value="#{datatableBean.lstData}"
                border="1" styleClass="table">
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="ID" />
                    </f:facet>
                    <h:outputText value="#{data.id}" />
                </h:column>
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Value" />
                    </f:facet>
                    <h:outputText value="#{data.value}" />
                </h:column>
            </h:dataTable>
        </h:form>
    </h:body>
</ui:composition>

UPDATE:

I've conducted tests in Chrome 18 and IE 9 regarding changing only the height of the td element:

height: 30px;

height: 50px;

height: 10px;

As demonstrated, adjusting the height of the td element impacts the row height. If you're experiencing issues, try accessing Tools / Internet Options, then under Browsing History select Settings. In the Temporary Internet Files section, check "Every time I visit the webpage," press OK, and refresh your website to view the changes.
