WOW thank you very much.
I think the newspaper column is kind of what I was looking for.
We might be able to use the schedule tag, which will make it look much
nicer.
Thanks for your help.

By the way, the key class here is
RowAndColumnRelationshipsBackingBean.java. This is how your backing
bean would be configured, with t:dataTable's value being your
rowDataModel and t:columns's value being your columnDataModel.
I have some more modern code using Facelets compositions rather than jsp:
<t:dataTable id="datatable"
value="#{backingBean.rowDataModel}"
var="row"
rows="10"
preserveDataModel="false"
border="1">
<f:facet name="footer">
<h:panelGroup>
<h:commandButton value="Update"
actionListener="#{backingBean.update}"/>
</h:panelGroup>
</f:facet>
<h:column>
<h:outputText value="#{row.rowName}"/>
</h:column>
<t:columns
value="#{backingBean.columnDataModel}"
var="column">
<f:facet name="header">
<h:outputText value="#{column.columnName}"/>
</f:facet>
<h:selectBooleanCheckbox
value="#{backingBean.relationshipValue}"/>
</t:columns>
</t:dataTable>
Implement your own RowAndColumnRelationshipsDataModel instances.
