我在

下有一个json（在我的控制器中） 
//creating an application module
var myAppModule = angular.module("myApp", []);


myAppModule.controller("MyCtrl", function($scope, $http){   

    var jsonData = [
                      {
                        "bucket": ">120",
                        "productCode": "SBML",
                        "countOfAllocatedAccount": 640                      
                      },
                      {
                        "bucket": ">120",
                        "productCode": "SBHL",
                        "countOfAllocatedAccount": 1391
                      },
                      {
                        "bucket": "1-30",
                        "productCode": "SBHL",
                        "countOfAllocatedAccount": 1081
                      },
                      {
                        "bucket": "1-30",
                        "productCode": "SBML",
                        "countOfAllocatedAccount": 408
                      },
                      {
                        "bucket": "1-30",
                        "productCode": "SBML",
                        "countOfAllocatedAccount": 998
                      },                      

                      {
                        "bucket": "X",
                        "productCode": "SBML+",
                        "countOfAllocatedAccount": 93
                      }
                    ];
            $scope.products = jsonData;

    });//end controller

和我的观点（index.html）在

下面 
<body ng-app="myApp">       
        <div ng-controller="MyCtrl" align="center">  
            <table border="1">
                <tr>

                      <th>Bucket</th>   
                      <th>PRODUCT_CODE</th>              
                      <th>Allocated #</th>                   
                </tr>
                <tr ng-repeat="p in products">

                      <td><span>{{p.bucket}}</span></td>                                     
                      <td><span>{{p.productCode}}</span></td>
                      <td><span>{{p.countOfAllocatedAccount}}</span></td>                     
                </tr>               
            </table>
        </div>      
    </body>
</html>

你可以这样做。

将当前的桶值与前一个桶值进行比较，如果它们相同，则不要显示它。 

<tr ng-repeat="p in products">
    <td><span ng-show="products[$index-1].bucket != p.bucket">{{p.bucket}}</span></td>                                     
    <td><span>{{p.productCode}}</span></td>
    <td><span>{{p.countOfAllocatedAccount}}</span></td>                     
</tr>
