columns and "multi line" header

[Hamsterbau]

Sorry you're right. columnClasses is only for panelGrid. rowStyleClass for rows and on each column styleClass for columns should work.

That works great with styleClass. Thank you !

Can you share your solution/workaround to satisfy your multi-line header requirement?

I am afraid I have changed my way.

With that as a beginning

Code: Select all

List<List<String>> tabDataList // contains the data and the "row headers" of the table
List<ColumnModel> tabHeaderModel // contains the first line of column headers
List<List<String>> restOfHeader // contains the rest of the lines of columns headers

I have tested and implemented with an inner dataTable, but I found it made the main table not clear.
The code was:

Code: Select all

<p:dataTable var="data" value="#{mainController.view.tabDataList}" id="tabularView">		
	<p:columns value="#{mainController.view.tabHeaderModel}" var="column" columnIndexVar="colIndex">
		<f:facet name="header">#{column.header}
			<p:dataTable var="datacol" column="1" value="#{mainController.view.restOfHeader[colIndex]}" rendered="#{colIndex ne null}">
				<p:column styleClass="ui-widget-header">
					#{datacol}
				</p:column>
			</p:dataTable>
		</f:facet>
		#{data[colIndex]}
	</p:columns>
</p:dataTable>

Another solution I have explored it to merge restOfHeader at the beginning of tabDataList, so the rest of the headers are considered as "normal" cells. You just have to applies them the style "ui-widget-header".
I was not so bad. A good alternative.

Finally I've concatened all my lines in the first cell, that's all...
For that, I walk in my 2 dimensionnal array ([][]) horizontally and vertically to concat the headers in one.
So I am able to use sort options, for example.

Hope it will help.
