<tr ng-repeat="emp in EmployeeRM">
            <td rowSpan="{{emp.rows}}" ng-if="! emp.matchPreviousRow">
                {{emp.Name}}
                <br />
                <button class="btn btn-primary" ng-click="" id="btnEmpStatus">Remind</button>
            </td>
            <td>{{emp.ProjectName}}</td>
            <td>
                {{emp.ProjectManager}}
                <button class="btn btn-primary" ng-click="" id="btnPMstatus">Remind</button>
            </td>
            <td>
                {{emp.ResourceManager}}
                <button class="btn btn-primary" ng-click="" id="btnRMstatus">Remind</button>
            </td>
        </tr>
    </table>

Angularjs controller code:

 .controller('RMDashboardCtrl', function ($scope, $http, $rootScope, $state) 
  {
      GetEmployeeRM();
       function GetEmployeeRM() {
        $http({
            url: 'EvalService.asmx/GetEmployeesforRM',
            params: { EmpId: $rootScope.Empid, fromDate: from_Date, toDate: 
                       to_date, year: year },
            method: 'GET'
               }).then(function (response) {
                 $scope.EmployeeRM = response.data;
                 console.log(response.data);
               if (response.data.length > 0) {
                response.data[0].matchPreviousRow = false;
                for (var i = 0; i < response.data.length; i++) {
                    var field = response.data[i].Name;
                var rows = 1;
                for (var j = i + 1; j < response.data.length; j++) {
                    if (response.data[j].Name === field)
                    {
                       rows++;
                       response.data[j].matchPreviousRow = true;
                    } else {
                        response.data[j].matchPreviousRow = false;
                        break;
                    }
                }
                response.data[i].rows = rows;
                }
            }
        });
    }

Thanks in advance
