The cell filter function

[varonica]

Can we use filter in datagrid ?

Example:
$('#dg').datagrid({
   columns:[[
      {field:'userId',title:'User', width:80,
         formatter: function(value,row,index){
            if (row.user){
               return row.user.name;
            } else {
               return value;
            }
         },
                        filter: function(v){
                             alert(v);
                        }
      }
   ]]
});
