Create a table from REST object by setting data in columnar manner - html

Question

I have a REST service, which returns this object:
[
{
"id": 100,
"value": "2452"
},
{
"id": 100,
"value": "2458"
},
{
"id": 1,
"value": "2457"
},
{
"id": 1,
"value": "2459"
},
{
"id": 4,
"value": "2460"
},
{
"id": 5,
"value": "3458"
}
]
Now, using this GET service, I want the following table to be built in angular and show it in UI.
100 1 4 5
-------------------
2452 2457 2460 3458
2458 2459
i.e. the unique ids should create the header and the list of values associates to each header value will be appended to respective column.
I have tried something with ng-repeat like this:
<table border="1">
<tr>
<th ng-repeat="column in cols">{{column.id}}</th>
</tr>
<tr>
<td ng-repeat="column in cols">
<md-list>
<md-list-item class="md-2-line" ng-repeat="val in column.values">
<md-checkbox ng-model="item.done"></md-checkbox>
<div class="md-list-item-text">
??
</div>
</md-list-item>
</md-list>
</td>
</tr>
But still wondering how to do the same? Please help.

Try use groupBy filter.
var app = angular.module('anApp', ['angular.filter']);
app.controller('aCtrl', function($scope) {
$scope.data = [
{
"id": 100,
"value": "2452"
},
{
"id": 100,
"value": "2458"
},
{
"id": 1,
"value": "2457"
},
{
"id": 1,
"value": "2459"
},
{
"id": 4,
"value": "2460"
},
{
"id": 5,
"value": "3458"
}
];
})
