如题。使用ng-table,在ng-repeat时用的data-title,标题却没显示出来（其他都正常）。如下图：

上代码：

// controller。 state中 controllerAs: posts
.controller('PostManageIndexCtrl', [
                '$scope',
                '$timeout',
                'PostService',
                'NgTableParams',
                function ($scope, $timeout, PostService, NgTableParams) {
                    var self = this;
                    self.$injet = ["NgTableParams", "ngTableSimpleList"];
                    this.posts = {};

                    self.tableParams = createUsingFullOptions();

                    // init
                    function createUsingFullOptions() {
                        var initialParams = {
                            page: 1,
                            sorting: { created_at: "desc" },
                            count:5
                        };
                        var initialSettings = {
                            counts: [5, 20, 50, 100],
                            paginationMaxBlocks: 5,
                            paginationMinBlocks: 2,
                            getData: function(params) {
                           // console.log(PostService.fnGetPosts(params, $scope.filterValue));
                                return PostService.fnGetPosts(params, $scope.filterValue);
                            }
                        };
                        return new NgTableParams(initialParams, initialSettings);
                    }

                    //删除
                    self.fnDestroyPost = function (id) {
                        PostService.fnDestroyPost(id);
                    };

                    //筛选
                    $scope.$watch("filterValue", function () {
                        console.log('aaa');
                        self.tableParams.reload();
                    }, true);

                }])
                
//接下来是html

<p class="row">
        <p class="col-xs-12">
            <p class="box">
                <p class="box-body">
                    <table  ng-table="posts.tableParams" class="table table-condensed table-bordered table-striped">
                        <tr ng-repeat="row in $data">
                            <td data-title="标题" sortable="'title'">[: row.title :]</td>
                            <td data-title="创建时间">[: row.created_at :]</td>
                            <td data-title="最后修改时间">[: row.updated_at :]</td>
                            <td data-title="操作">
                                <a style="margin:3px;" ui-sref="post.postManageEdit({postId:row.id})" class="X-Small btn-xs text-success ">
                                    <i class="fa fa-edit"></i> 编辑
                                </a>
                                <a style="margin:3px;" ng-click="posts.fnDestroyPost(row.id)" class="delBtn X-Small btn-xs text-danger ">
                                    <i class="fa fa-times-circle-o"></i> 删除</a>
                            </td>
                        </tr>
                    </table>
                </p>
            </p>
        </p>
    </p>

controller 中的console数据如下

控制台中报错如下：

*n

我用 ng-table-dynamic 的 self.cols 形式标题倒是没问题，就是我要加那个操作那个td内容不知道该怎么加进去。

求各位大神帮帮忙，感激不尽啊！！！磕头
