How to get rid of border / rules / frame with rich:dataGrid

[cdiggins]

I have the bottom and right of each dataGrid cell showing a line, and I would like to get rid of it. I have the following - which does not help at all except to get rid of the top and left sides...bottom and right remain:

<rich:dataGrid columns="#{attributeGroup.numColumns}" elements="100" var="activityAttributeValue"
value="#{attSubGroup.groupedAttributes}" frame="void" border="0" cellpadding="0" cellspacing="0" >

attribute border and css rules for border are not the same thing in html.
