Hi,
The crosstable component makes it possible to have a variable count of
columns in a datatable.
The component is working like this:
<x:dataTable value="#{data.rows}" var="row" >
<!-- just a column -->
<h:column>
<f:facet name="header">
<h:outputText value="fixed column" />
</f:facet>
<h:outputText value="#{row.attributeName}" />
</h:column>
<!-- new columns component renders a column for each element in
data.columns -->
<x:columns value="#{data.columns}" var="column">
<f:facet name="header">
<!-- row is not available! -->
<h:outputText value="#{column.label}" />
</f:facet>
<!-- row is also available -->
<h:outputText value="#{data.columnValue}" />
<f:facet name="footer">
<!-- row is not available! -->
<h:outputText value="#{column.footer}" />
</f:facet>
</x:columns>
</x:dataTable>
The x:columns component is based on UIData. The parent datatable must
have a fixed count of columns so it is not possible to use <x:columns
value="#{row.columns}" var="column">.
To get the value for the column in the row a managed bean must be used
which calls DataModel.getRowData() from the rows datamodel and the
columns datamodel to determine the current row and column.
