Angular ng-repeat table：来自 object 的动态列

Question

我正在尝试创建一个看起来像这样的 table:

20       23        25       26
734.53   279.20    936.95   584.50

基于此Object:

{
    "20": 734.5339864003384,
    "23": 279.20378246766563,
    "25": 936.9526667106079,
    "26": 584.5060233468447,
    "27": 279.20378246766563,
    "28": 2055.970661511549,
    "29": 1405.0981690224412,
    "30": 549.4917661928141,
    "31": 2329.1464674575695,
    "32": 147.8822594632703,
    "33": 698.0104349592335
}

显然列的标题需要根据JSON的键和值进行动态对应。

我有以下代码，但我完全不确定我是否在正确的轨道上：

JS

 $scope.modal = {};
    $scope.modal.keys = [];
    $scope.modal.data = [];
    for (var key in assets.total) {
      if (assets.total.hasOwnProperty(key)) {
        $scope.modal.keys.push(key);
        $scope.modal.data.push(assets.total[key]);
      }
    }

HTML

<table class="table table-striped">
  <thead>
    <tr>
      <th ng-repeat="th in modal.key">{{th}}</th>
    </tr>
  </thead>
  <tbody></tbody>
    <tr ng-repeat="x in modal.data">
      <td ng-repeat="th in modal.key">{{x[th]}}</td>
    </tr>
  </tbody>
</table>

它只是不起作用我只用一列得到了一个奇怪的结果。

您可以试试这个解决方案

使用 ng-repeat="(key, value) in Array" 获取对象中的键值。

我已经在 Working Demo on Stackblitz

上创建了一个演示

并删除 for (var key in assets.total) 循环。

html代码

<table class="table table-striped">
    <thead>
        <tr>
        <th ng-repeat="(key, value) in data"> {{key}} </th>
        </tr>
    <tr>
        <td ng-repeat="(key, value) in data"> {{ value| number: 2 }} </td>
        </tr>
    </tbody>
</table>

Js file code

$scope.data = {
      "20": 734.5339864003384,
      "23": 279.20378246766563,
      "25": 936.9526667106079,
      "26": 584.5060233468447,
      "27": 279.20378246766563,
      "28": 2055.970661511549,
      "29": 1405.0981690224412,
      "30": 549.4917661928141,
      "31": 2329.1464674575695,
      "32": 147.8822594632703,
      "33": 698.0104349592335
