JSF's rich:datatable allows for displaying lengthy text in columns across multiple lines

On a JSF .xhtml page, I am using a richdatatable and have encountered an issue with displaying long text in a particular cell. How can I set the width of the column to ensure that the text wraps around and displays properly within the specified cell? As someone who is new to JSF and CSS, I'm unsure of where to make adjustments in the code. Here's an example scenario: if I have two columns in a richdatatable and one of them contains very long text, how do I ensure that the text is displayed in multiple lines (wraps text) rather than on a single line?

<ui:composition template="/template.xhtml">
    <ui:define name="title">
        <h:outputText value="#{bundle.ViewFileTitle}"></h:outputText>
    </ui:define>
    <ui:define name="body">
    <h:form>
            <rich:dataTable value="#{fileController.feedbackFileItems}" var="item" id="table">
                    <rich:column>
                       <f:facet name="header">
                            <h:outputText value="#{bundle.ListFeedbackTitle_feedbackPK_feedbackId}"/>
                        </f:facet>
                        <h:outputText value="#{item.feedbackPK.feedbackId}"/>
                    </rich:column>
                    <rich:column>
                        <f:facet name="header">
                            <h:outputText value="#{bundle.ListFeedbackTitle_department}"/>
                        </f:facet>
                        <h:outputText value="#{item.department}"/>
                    </rich:column>
            </rich:dataTable>
            </form>
    </ui:define>
</ui:composition>

Answer №1

When you need to display long text in multiple lines, you have the option to use the width attribute within the rich:column tag:

<rich:column width="150" ...>

You can also achieve the same effect with the h:column tag:

<h:column width="110">

If you prefer not to display text in a datatable cell on multiple lines, there are a couple of approaches you can take:
1) You can utilize the columnClasses attribute of the rich:dataTable tag and specify a no-wrap style for that column. For example:

<rich:dataTable columnClasses="nowrap,">

with the following CSS:

.nowrap {
    white-space: nowrap;
}

This will result in a table where the first column is not wrapped.

2) Alternatively, you can use the style or styleClass attributes within the rich:column tag to achieve the same result (using the same CSS).
