columnClasses in HtmlDataTable

[seb petterson]

Is there a way to tell a dataTable that the styles you declare are to belong to the columns you declare in in jsf tags in the order they appear, and not simply to the columns that are rendered?

<h:dataTable value="#{bean.data}" var="data" 
columnClasses="col1, col2, col3" >
 <h:column id="col1" rendered="#{rules.col1Rendered}">
 <h:outputText value="data.col1data"/>
 </h:column>
 <h:column id="col2" rendered="#{rules.col2Rendered}">
 <h:outputText value="data.col2data"/>
 </h:column>
 <h:column id="col3" rendered="#{rules.col3Rendered}">
 <h:outputText value="data.col3data"/>
 </h:column>
</h:dataTable>

In this example if #{rules.col2Rendered} returns false and the others return true, then the styles col1, col2 will be assigned to the columns with id "col1" and "col3" since theyre the only ones rendered, instead I want these to have the styleClasses col1 and col3. How do I achieve this?

I guess there is not. Instead I will get a string for columnClasses from bean method that calculates which styleclasses should be used. I don't like to have stuff that I feel belongs in web content files (jsps etc.) in java code, but oh well.

For what it's worth, you'll want to use the <h:dataTable> tag instead; that caters for repeating rows.

Yes, the work around you suggested is the best way to do it. I have done in lot of pages (even it costs specifing the styleclass name in the java file)

why dont you use the condition and respective column classes within columnClasses attribute.

i mean [B]

columnClasses="#{somecondition ? 'class1, class2':'class1, class2, class3'}"

[/B]

Hope this works.

One possible workaround is to filter the list prior to rendering, i.e. have a copy of the list and the set the filtered list to the data table so that you can still use the columnClasses attribute in the data table.

I had the same problem and I just tried Puneet Swarup's solution -which I believe to be the most elegant of the ones proposed thus far here. It worked perfectly. I had struggled to try to do the same with the A?B:C conditional notation but had failed time and time again. I would have continued to bang my head against the wall for hours had it not been for this thread. I never would have imagined that I had to enclose the columnClasses values in simple apostrophes ('). It's still a little confusing to me when to and not to use apostrophes. So, thanks a million, Swarup.
