Is there a way to stop richfaces from adding all those styles to the datagrid? I know its supposed to be easily templated, but I don't want the same styles for every table in my site. Setting the styles for columns table cells ect just tacks them one along with the standard richfaces styles so the page is TONS bigger then it needs to be (on large tables it does matter)
No. Predefined styles - is a skinability feature implementation.
