dojox.grid.datagrid null values not rendered IE7

[dave.wilton]

Null cells do not have a border outline in IE7. The solution is to override the following CSS property:

/* IE7 bug causes null cells not to have a border. */
.dj_ie .claro .dojoxGridMasterView .dojoxGridRowTable
{
    border-collapse: collapse
}
