在页面上显示数组

我有数组,其中每个对象都有包含数组对象的字段,例如:

var objects = [{
       'id':'1',
       'name': 'Joe',
       'last': 'Doe',
       'additionalField': {
           "a":[1,2,3],
           'b':[4,5,6],
           'c':[7,8,9],
           'd':[7,8,9],
       }, {...}, ...
 }]

我如何在模板中设置additionalField? 现在我转换数组矩阵,并显示如下:

<tr ng-repeat="field in transposed">
    <td ng-repeat="element in field">
        <a ng-click="someAction(elment.name, elment.value)">{{element.value}}</a>
    </td>
</tr>

当我转置矩阵时,我会构建像:

这样的对象
var transposed = [
   [{'name': 'a', 'value': '1'},
    {'name': 'b', 'value': '4'},
    {'name': 'c', 'value': '7'}],
   [{'name': 'a', 'value': '2'},
    {'name': 'b', 'value': '5'},
    {'name': 'c', 'value': '8'}],
]

但似乎太复杂了。你知道我怎么能这么简单吗?我的意思是我可以在没有移调的情况下这样做吗?获取表格如下:

1 4 7 7
2 5 8 8
3 6 9 9

如果您的对象数组如下:

if __name__ == '__main__':
    test()

并希望显示如下:

$scope.objects= [{
       'id':'1',
       'name': 'Joe',
       'last': 'Doe',
       'additionalField': {
           "a":[1,2,3],
           'b':[4,5,6],
           'c':[7,8,9],
           'd':[7,8,9],
       }
 }];

然后可以尝试:

1 4 7 7
2 5 8 8
3 6 9 9

您可以像这样转置矩阵:

var transposed = [
   [{'a': '1'},
    {'b': '4'},
    {'c': '7'}],
   [{'a': '2'},
    {'b': '5'},
    {'c': '8'}]
]

在页面上显示如下:

<tr ng-repeat="field in transposed">
    <td ng-repeat="value in field">
        <a ng-click="someAction($index, value)">{{value}}</a>
    </td>
</tr>
