    title: 'grid',
    height: 200,
    width: 200,
    renderTo: Ext.getBody(),
    columns: [{
        text: 'Col',
        dataIndex: 'col',
        renderer: function (val, metadata, record) {
            if (record.get('col') == 1) {
                metadata.style = 'background-color: #FFFFCC !important;cursor: pointer;'
            }
            return val;
        },
        listeners:{
             "click":function(grid,cell,row){
                      var r =  grid.store.getAt(row);
              }
       }
