Some attributes such as rules, frame, borderColorDark, border, etc are not avaible in the datagrid. Even if I use some those properties in a css I could not get the visual effect that I wished. Also the expression language are not avaible for some attributes, example styleClass of a column I can´t use EL. Maybe it´s better to put the expression language for all values.
