angularjs - How can I use a filter to all field in ng-table -

hi i'm learning angularjs, , i'm using ng-table, not know how multiple filter in 1 field.

i know how 1 filter , sorting, searched , read couldn't find working me, guess there way.

thanks , pardon english.

edit: thats code

$scope.init = function () { $http.post(slim + 'grupos2', $.extend({}, false, window.seguridad)).then(function(response) { $scope.grupos = response;
var data2 = $scope.grupos.data;

            $scope.tableparams = new ngtableparams({                 page: 1,                           count: 10,                         filter: {                  },                  sorting: {                 nombre: 'asc'                          }             }, {             total: data2.length,              getdata: function($defer, params) {                var ordereddata = params.filter() ?                  $filter('filter')(data2, params.filter()) :                  data2;                ordereddata = params.sorting() ?                  $filter('orderby')(ordereddata, params.orderby()) :                  ordereddata;                  $scope.grupete = ordereddata.slice((params.page() - 1) * params.count(), params.page() * params.count());                  params.total(ordereddata.length);                  $defer.resolve($scope.grupete);          }     }); }); 

and

            <tr ng-repeat="grupo in grupete">                 <td data-title="'num'" sortable="'idgrupo'">{{grupo.idgrupo}}</td>                 <td data-title="'name'" sortable="'name'" filter="{ 'name': 'text' }" >{{grupo.nombre}}</td>                 <td data-title="'aforo'" sortable="'aforo'" >{{grupo.aforo}}</td>                 <td data-title="'fecha'" sortable="'fecha'" >{{grupo.fecha.tostring()}}</td>              </tr>         </table>    

i want there filter searches multiple fields name.

filter="{ 'name': 'text' }"

the exact behaviour looking accomplished using filter object '$' attribute. this:

  $scope.tableparams = new ngtableparams({     // ...            filter: {       $: 'filter string'     },   }, {     // ...   });
