AngularJs ng-repeat 2D array in table, each subarray one column - arrays

Question

I have an array and I need to put that array in table.
$scope.testArr=[
{'first':[
{ 'value':'1_1', 'rolle':'one1' },
{ 'value':'2_1', 'rolle':'two1' },
{ 'value':'3_1', 'rolle':'three1'}
]
},
{'second': [
{ 'value':'1_2', 'rolle':'one2' },
{ 'value':'2_2', 'rolle':'two2' },
{ 'value':'3_2', 'rolle':'three2' }
]
}
];
Resulting table should have 4 columns, each subarray should be one(or two) column(s). Like this:
one1 | 1_1 | one2 | 1-2
two1 | 2_1 | two2 | 2_2
three1|3_1 | three2|3_2
So far I got this. Its only the first subarray:
<table>
<tbody ng-repeat="test in testArr">
<tr ng-repeat="t1 in test.first">
<td> {{t1.rolle}} </td>
<td> {{t1.value}} </td>
</tr>
</tbody>
</table>
How can I add the second subarray as column? It's not necessary need to be a table.

var app = angular.module('app', []);
app.controller('mainCtrl', function ($scope) {
$scope.testArr = [{
'first': [{
'value': '1_1',
'rolle': 'one1'
}, {
'value': '2_1',
'rolle': 'two1'
}, {
'value': '3_1',
'rolle': 'three1'
}]
}, {
'second': [{
'value': '1_2',
'rolle': 'one2'
}, {
'value': '2_2',
'rolle': 'two2'
}, {
'value': '3_2',
'rolle': 'three2'
}]
}];
});
td {
border:solid 1px grey
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="mainCtrl">
<table>
<tbody ng-repeat="test in testArr">
<tr ng-repeat="t1 in test.first">
<td>{{t1.rolle}}</td>
<td>{{t1.value}}</td>
<td>{{testArr[1].second[$index].rolle}}</td>
<td>{{testArr[1].second[$index].value}}</td>
</tr>
</tbody>
</table>
