DataTable dynamic columns and grouping

[zambrovski]

Hi Folks,

Thanks for improving the Primefaces...

I'm trying to combine two powerfull features of Primefaces 2.2 : dynamic columns and column grouping. My task is to create a two level header: in the first level header, the columns have a colspans of three and the second level header is just a normal one. The difficulty is thst the header must be dynamic.

I tried this:

Code: Select all

<p:dataTable var="swimlane" value="#{scheduleController.swimlanes}">
	          <p:columnGroup type="header">
			<p:row>
				<ui:repeat var="dayHeader" value="#{scheduleController.columns}">  
					<p:column colspan="3" headerText="#{dayHeader.offset}" />															
   				</ui:repeat> 				
			</p:row>
			<p:row>
				<ui:repeat var="shiftHeader" value="#{scheduleController.shifts}">  
					<p:column headerText="#{shiftHeader.shift}" />															
   				</ui:repeat> 				
			</p:row>
		</p:columnGroup>
         <...>

But it doesn't work. And <p:columns> doesn't support colspan/rowspan attributes.


Any ideas?


Kind regards,

Simon

P.S. Just bought the manual but didn't find the answer there...

We've never tried merging these two features together so if you think there is a limitation here, feel free to create an enhancement request.

I've had this same issue and I've noticed that c:forEach works well:

Code: Select all

<p:columnGroup id="colGroup" type="header" >
<p:row >
	<p:column colspan="1" width="20"  />
	<p:column colspan="3" headerText="Information" width="360" />

	<c:forEach items="${yardMaster.blockVolHours}" var="hour" >
		<p:column colspan="${hour.colspan}" headerText="${hour.hour}" width="${hour.colspan * 90}" />
	</c:forEach>
</p:row>

<p:columnGroup id="colGroup" type="header" >
<p:row >
	<p:column colspan="1" width="20"  />
	<p:column colspan="3" headerText="Information" width="360" />

	<c:forEach items="${yardMaster.blockVolHours}" var="hour" >
		<p:column colspan="${hour.colspan}" headerText="${hour.hour}" width="${hour.colspan * 90}" />
	</c:forEach>
</p:row>

i have tried as you said above, but it is not working for me.

And My Xhrml Code is here below :

Code: Select all

<p:dataTable value="#{templateBean.headerRows}" var="row" id="tab2"
                  style="width:100%;overflow:auto;"
                  emptyMessage="Template Preview is not available">
                  <p:columns value="#{templateBean.headerPreview}"
                     style="height:20px;" headerText=" #{column}" var="column">
                     <f:facet name="header">
                        <h:outputLabel value="#{column}" />
                     </f:facet>
                     <h:outputLabel value="#{row[column]}" rendered="false" />
                  </p:columns>
               </p:dataTable>

Can you explain clearly please?
