Create html table using angular
I want to create an html table using angular. I have a json object and I used ng-repeat to add multiple lines. But my table structure is different. I want to create a table structure like this:
<table>
<tr>
<td >ID</td>
<td>Sub</td>
</tr>
<tr>
<td rowspan="3">1</td>
<td>S1</td>
</tr>
<tr>
<td>S2</td>
</tr>
<tr>
<td>S3</td>
</tr>
</table>
--------------
ID | subjects
--------------
| S1
--------
1 | S2
--------
| S3
--------------
| S4
--------
2 | S5
--------
| S6
--------------
user:[
{id:1 ,
subjects:[
{id:1 , name:"eng"}
{id:2 , name:"phy"}
]
},
{ id:2 ,
subjects:[
{id:1 , name:"eng"}
{id:3 , name:"math"}
]
}
]
my angular code:
<tr ng-repeat = "user in users">
<td>{{user.id}}</td>
<td>{{user.subject}}</td>
</tr>
I want to know how to create a table structure as shown above

You need to use ng-repeat-start
and ng-repeat-end
. For example:
var app = angular.module('MyApp', []);
app.controller('MyController', function ($scope) {
var users = [{
id: 1,
subjects: [{
id: 1,
name: "eng"
}, {
id: 2,
name: "phy"
}]
}, {
id: 2,
subjects: [{
id: 1,
name: "eng"
}, {
id: 3,
name: "math"
}]
}];
$scope.users = users;
});
table { border-collapse: collapse; }
td { border: 1px solid Black; }
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<table ng-app="MyApp" ng-controller="MyController">
<thead>
<tr>
<td>ID</td>
<td>Subjects</td>
</tr>
</thead>
<tbody>
<tr ng-repeat-start="user in users">
<td rowspan="{{user.subjects.length+1}}">{{user.id}}</td>
</tr>
<tr ng-repeat-end ng-repeat="subject in user.subjects">
<td>S{{subject.id}}</td>
</tr>
</tbody>
</table>

I have split your JSON and put it in two variables $scope
as shown below:
angular.forEach($scope.user, function(user) {
$scope.userDetails.push({
userId: user.id,
});
angular.forEach(user.subjects, function(subject) {
$scope.subjectDetails.push({
userId: user.id,
subjectName: subject.name
});
});
});
In HTML I use filter
to filter by user id.
<table>
<thead>
<tr>
<th style="width: 50px">ID</th>
<th style="width: 75px">Subjects</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="user in userDetails">
<td><span ng-bind="user.userId"></span>
</td>
<td>
<table>
<tr ng-repeat="sub in subjectDetails | filter: {userId: user.userId}">
<td>
<div ng-bind="sub.subjectName"></div>
</td>
</tr>
</table>
</td>
</tr>
</tbody>
</table>
This is also one way to achieve this.
Example Plunker

add users to $ scope.
$scope.users=[
{id:1 ,
subjects:[
{id:1 , name:"eng"}
{id:2 , name:"phy"}
]
},
{ id:2 ,
subjects:[
{id:1 , name:"eng"}
{id:3 , name:"math"}
]
}
]
Here is the html.
<table border="1">
<tr>
<th> ID </th>
<th> subjects </th>
</tr>
<tr ng-repeat="user in users">
<td>{{user.id}}</td>
<td><table>
<tr ng-repeat="subject in user.subjects">
<td>{{subject.name}}</td>
</tr>
</table></td>
</tr>
</table>
Here is the plunker

Here I am assuming you want every user in users (in your JSON object) to be in the same table, so you can do something like this:
<table ng-repeat="user in users">
<tr>
<td>{{user.id}}</td>
<td>Subjects</td>
</tr>
<tr ng-repeat="subject in user.subjects">
<td>{{subject.id}}</td>
<td>{{subject.name}}</td>
</tr>
</table>
Adjust the html accordingly based on your needs, but that's the main idea :)
Hope this helps!
