angularjs – 角网格网格列.Defs动态变化

$scope.gridOptions = {
        columnDefs: [],enableFilter: true,rowData: null,rowSelection: 'multiple',rowDeselection: true
    };

当我从服务器检索数据时：

$scope.customColumns = [];

$http.post('/Home/GetProducts',{ tableName: 'TABLE_PRODUCT' }).success(function (data) {
    angular.forEach(data.Columns,function (c) {
        $scope.customColumns.push(
            {
                headerName: c.Name,field: c.Value,width: c.Width
            }
        );
    });

    $scope.gridOptions.columnDefs = $scope.customColumns;

    $scope.gridOptions.rowData = data.Products;
    $scope.gridOptions.api.onNewRows();
}).error(function () {

});

注意：这里c是来自服务器的列对象.

当动态生成列并将其分配给$scope.gridOptions.columnDefs时,会出现空格,但是$scope.customColumns数组将填充右边生成的列对象.请帮助我是这个bug还是我做错了？
