我想在表格中交换2列。最后,我成功完成了更改,但只有数据。单元格的属性(样式,id,类)没有移动。我试图用jquery移动属性(我知道,不是一种优雅的方法),但它只是对症处理。单击数据重新加载按钮后,属性将恢复。 如何使用所有属性更改列顺序?

您可以将颜色绑定到标题名称:
$scope.styles = {
id: "yellow",
name: "pink"
};
和表格如下:
<tr ng-repeat="row in rows">
<td class="o1" ng-style="{'background-color':styles[mycol[0]]}">{{col(row, 0)}}</td>
<td class="o2" ng-style="{'background-color':styles[mycol[1]]}">{{col(row, 1)}}</td>
<td class="o3" style="background-color:green;">{{col(row, 2)}}</td>
<td class="o4" style="background-color:blue;">{{col(row, 3)}}</td>
</tr>
标题值更改后,颜色也会发生变化
您可以通过将所有表替换为指令(标题+数据)并使用$compile重建所有HTML表来实现它。
