Question

我的专栏是一个计算列，例如{{desserts.value1 / desserts.value2}}

 <md-table-container>
  <table md-table>
    <thead md-head md-order="myOrder">
      <th md-column md-order-by="value1">Dessert (100g serving)</th>
      <th md-column md-order-by="????">Calories</th>
    </thead>
    <tbody md-body>
      <!-- we can let ng-repeat sort the columns for us -->
      <tr ng-repeat="dessert in desserts | orderBy: myOrder">
        <td>{{ dessert.value1}}</td>
        <td>{{ (dessert.value1 == 0)?0 : dessert.value2)}}</td>
    </tr>
    </tbody>
  </table>
</md-table-container>

我想订购那个列，那么我应该在md-order-by中给出什么，通常我可以给出属性名称。

Answer 1

当我单独给出它没有物体的价值时，它将需要。 ie（（value1 == 0）？0：value2）

<md-table-container>
  <table md-table>
    <thead md-head md-order="myOrder">
      <th md-column md-order-by="value1">Dessert (100g serving)</th>
      <th md-column md-order-by="(value1 == 0)?0 : value2)">Calories</th>
    </thead>
    <tbody md-body>
      <!-- we can let ng-repeat sort the columns for us -->
      <tr ng-repeat="dessert in desserts | orderBy: myOrder">
        <td>{{ dessert.value1}}</td>
        <td>{{ (dessert.value1 == 0)?0 : dessert.value2)}}</td>
    </tr>
    </tbody>
  </table>
</md-table-container>
