I have added some changes to the tables to add sortable columns like in the listview property editor.

As a starting point I have done this with the keywords table. I think the sorting could use the default icons for sorting like icon-sort (which listview property editor also use), icon-caret-down and icon-caret-up. But it seems these icons are missing in Umbraco as the listview doesn't display the sort direction. Issue created here: http://issues.umbraco.org/issue/U4-4688

So I have modified keywords.html and Keyword.Controller.js + added a new folder "/App_Plugins/Analytics/backOffice/AnalyticsTree/icons/" where I have copied the folder /css and /fonts from font-awesome-4.1.0 just to include the sorting icons. Perhaps there is a better way to do this.

keywords.html

<div ng-controller="Analytics.KeywordController">
    <div class="umb-pane">

        <div ng-model="dateFilter" date-range-picker class="pull-right" style="background: #fff; cursor: pointer; padding: 5px 10px; border: 1px solid #ccc">
        </div>   

        <h4>Keywords</h4>

        <div class="clearfix"></div>
        <div ng-show="loadingViews">
            <div class="umb-loader" style="height: 10px; margin: 10px 0px;"></div>
        </div>

        <table class="table table-striped">
            <thead>
                <tr>
                    <th id="keyword"><a href="#" ng-click="sort('keyword')" prevent-default>Keyword <i class="fa fa-sort"></i></a></th> <!-- icon-sort -->
                    <th id="visits"><a href="#" ng-click="sort('visits')" prevent-default>Visits <i class="fa fa-sort"></i></a></th>
                    <th id="pageviews"><a href="#" ng-click="sort('pageviews')" prevent-default>Page Views <i class="fa fa-sort"></i></a></th>
                </tr>
            </thead>
            <tbody>
                <tr ng-repeat="item in items | orderBy:sortField:descending">
                    <td>{{ item.keyword }}</td>
                    <td>{{ item.visits }}</td>
                    <td>{{ item.pageviews }}</td>
                </tr>
            </tbody>
        </table>

    </div>
</div>

Keyword.Controller.js

angular.module("umbraco").controller("Analytics.KeywordController",
    function ($scope, $location, statsResource, settingsResource, assetsService) {

            $('th i').each(function () {

            settingsResource.setDateFilter($scope.dateFilter.startDate, $scope.dateFilter.endDate);
            //Get Profile
            settingsResource.getprofile().then(function(response) {
                $scope.profile = response.data;
                profileID = response.data.Id;

                if (profileID == null || profileID == "") {
                    $location.path("/analytics/analyticsTree/edit/settings");
                    return;
                }
                $scope.loadingViews = false;
                //Get Browser via statsResource - does WebAPI GET call
                statsResource.getkeywords(profileID,$scope.dateFilter.startDate, $scope.dateFilter.endDate).then(function (response) {

                    angular.forEach($scope.keywords.Rows, function (item) {
                        $scope.items.push({
                            keyword: item.Cells[0],
                            visits: parseInt(item.Cells[1]),
                            pageviews: parseInt(item.Cells[2])
                        });
                    });

                    var defaultSort = "pageviews"; // default sorting
                    $scope.sortField = defaultSort;
                    $scope.descending = true;

                    $('th i').each(function () {
                        $(this).removeClass().addClass('fa fa-sort'); //icon-sort // reset sort icon for columns with existing icons
                    });
                    if ($scope.descending)
                        $('#' + defaultSort + ' i').removeClass().addClass('fa fa-sort-down'); //icon-caret-down
                    else
                        $('#' + defaultSort + ' i').removeClass().addClass('fa fa-sort-up'); //icon-caret-up

                    //$scope.filteredItems = [];


                    //var chartData = response.data.ChartData;

                    ////Create Bar Chart
                    //var ctx = document.getElementById("keywords").getContext("2d");
                    //var keywordsChart = new Chart(ctx).Bar(chartData);
                });

            });
        });

        //load the seperat css for the editor to avoid it blocking our js loading
        assetsService.loadCss("/umbraco/assets/css/umbraco.css");
        assetsService.loadCss("/App_Plugins/Analytics/backOffice/AnalyticsTree/icons/css/font-awesome.css");
    });

It looks like this:
