I am aware of the loadStyle tag. But I do not know what value I should fill for the src attribute to have css class such as dr-rich-table-cell and dr-rich-table-row available for my page.
This class is available automatically if rich:datatable is used in the page.
Please try to do the following:
1. Download source archive
2. Navigate into org\richfaces\renderkit\html\css package and find the required class name in XCSS files located there
<a4j:loadScript src="resource:///org/richfaces/renderkit/html/css/ filename.xcss" />
Please excuse me, should be:
<a4j:loadSyle src="resource:///org/richfaces/renderkit/html/css/filename.xcss" />
