Nomatter what I set in the frame attribute(void lhs etc.), right and bottom lines are drawn.
Tried this for instance
<rich:dataGrid rowClasses="top" value="#{buy.list}" var="list" columns="4" width="95%" border="0px" rules="none" frame="void">
Looking at the dom tree in firebug shows that css class dr-table-cell has the following attributes:
border-bottom:1px solid #000044;
border-right:1px solid #000044;
Is there any way to remove these borders?
