Specify the alignments for the column header and data

[dxxvi]

I define a rich:column like this

<rich:column>
 <f:facet name="header">
 <h:panelGroup>
 <a4j:commandLink ... /><h:outputText ... />
 </h:panelGroup>
 </f:facet>
 <h:outputText ... />
</rich:column>

By default, the header is center-aligned and the data is left-aligned. How can I make the header and data be aligned in a different way?

Use CSS:

.rich-table-cell{
 text-align: center;
 }
