Serial Number using nested NG-Repeat - angularjs

Question

I want to add serial number in each question
ng-repeat = "Table in Paper"
Display table
ng-repeat = "question in question"
(1) Display question
(2) Display question
I can use $index in Question. But for each Table, it is started from 1.
E.g.
Table 1
Question 1
Question 2
Table 2
Question 1
Question 2
But I want
Table 1
Question 1
Question 2
Table 2
Question 3
Question 4
I use $parent & $index. But not working.
<div ng-repeat="section in Table">
<div ng-repeat="question in section.question">
<span >{{(Section[$parent.$index-1].question.length + $index + 1 )+
'. ' +
question
.Description}}</span>
</div>

Answer 1

try this.
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', ["$scope",function MyCtrl($scope) {
$scope.lastIndex = 0;
$scope.lastIndexes = [];
$scope.Table ={
"table1":
{
"question":["questionA","questionB","questionC","questionD"]
},
"table2":
{
"question":["questionA","questionB","questionC","questionD"]
},
"table3":
{
"question":["questionC","questionD","questionF"]
},
"table4":
{
"question":["questionC","questionD","questionE"]
}
};
$scope.setLastIndex = function(len){
$scope.lastIndex = $scope.lastIndex + len*1;
$scope.lastIndexes.push($scope.lastIndex);
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<div ng-repeat="(key,value) in Table"
ng-init="setLastIndex(value.question.length)">
{{key}}
<div ng-repeat="question in value.question" >
<span>{{($index+1 +lastIndexes[$parent.$index-1])}} :{{question}}</span>
</div>
</div>

Answer 2

use
<div ng-repeat = "Table in Paper">
<div ng-repeat="q in Table.questions">
{{q}}
</div>
</div>
Here questions is array and present in your json

Answer 3

This may not the perfect solution what I want, But It can be a temporary solution,
Create watch or function in controller to traverse all question
var index=1;
Section.forEach(function (section) {
section.question.forEach(function (question) {
question.Number= index;
index++;
})
})
Then Print this number in ng-repeat
<div ng-repeat="section in Table">
<div ng-repeat="question in section.question">
<span >{{question.Number +'. ' +question.Description}}</span>
</div>
</div>
