如何使用 Angularjs 中的 orderBy 将字母表显示为 table 中的第一条记录？

Question

大家好，我正在研究 angularjs 以显示 table 中的记录列表。我面临的困难是按升序显示 table，我使用了我需要显示的字母表记录 (X) 在 table.

中有第一条记录

让我给你 html 页。

<table class="table table-bordered">
    <thead>
        <tr>
            <th ng-click="sort('bucket')" th-sort by="order">Bucket<span class="sortorder descending" ng-hide="(sortKey=='bucket' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='bucket' && reverse==false)"></span>
            </th>
            <th ng-click="sort('productCode')" th-sort by="order">Product Code<span class="sortorder descending" ng-hide="(sortKey=='productCode' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='productCode' && reverse==false)"></span>
            </th>
            <th ng-click="sort('countOfAllocatedAccount')" th-sort by="order">Allocated
                <span class="sortorder descending" ng-hide="(sortKey=='countOfAllocatedAccount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='countOfAllocatedAccount' && reverse==false)"></span>
            </th>
            <th ng-click="sort('countOfCollectedAccount')" th-sort by="order">Collected
                <span class="sortorder descending" ng-hide="(sortKey=='countOfCollectedAccount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='countOfCollectedAccount' && reverse==false)"></span></th>
            <th ng-click="sort('sumOfArrearsOfAllocatedAmount')" th-sort by="order">Total Allocated Amount
                <span class="sortorder descending" ng-hide="(sortKey=='sumOfArrearsOfAllocatedAmount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='sumOfArrearsOfAllocatedAmount' && reverse==false)"></span>
            </th>
            <th ng-click="sort('sumOfCollectedAmount')" th-sort by="order">Total Collected Amount
                <span class="sortorder descending" ng-hide="(sortKey=='sumOfCollectedAmount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='sumOfCollectedAmount' && reverse==false)"></span></th>
        </tr>
    </thead>
    <tbody>
        <tr ng-repeat="item in view_data">
            <td><span ng-hide="view_data[$index-1].bucket == item.bucket">{{item.bucket}}</span></td>
            <td>{{item.productCode}}</td>
            <td>{{item.countOfAllocatedAccount}}</td>
            <td>{{item.countOfCollectedAccount}}</td>
            <td><span>{{item.sumOfArrearsOfAllocatedAmount | currency:"&#8377;"}}</span></td>
            <td>{{item.sumOfCollectedAmount | currency:"&#8377;"}}</td>
        </tr>
    </tbody>
</table>

让我向您展示输出：

这是我的 jsfiddle：http://jsfiddle.net/CvKNc/152/

如图所示，存储桶值 X 是 table 中的最后一个值。但是，我需要将它显示在 table 的第一行，其余数字应按升序设置。我被困在这里，请任何人帮助我。
