SAP.m crosstab small hierarchy expand symbols

Hi guys,

I'm using the sap.m template for a mobile app. This app contains a crosstab component with a structure/hierarchy. The problem is that the plus/minus symbols that are used to expand the hierarchy nodes are pretty small when using on an iPhone. See the attached screenshot example.

I already did some CSS tweaking in .sapzencrosstab-HeaderCellDivHierarchy  to make the click area a bit bigger, but it is still hard to press at the right

spot.

.table1 .sapzencrosstab-HeaderCellDivHierarchy{    height:32px;    width:20px !important;    margin-right:0px !important;    margin-left:-2px !important;    background-position:0% 50% !important;    background-repeat:no-repeat    }

What I really would like is to have the whole cell area clickable. Can this be done using the CSS?

Thanks,

Xavier
