I want to generate table contents using json object. I am using ng-repeat to insert multiple rows in a table. But I have to generate table like the following.
--------------
ID | subjects
--------------
| S1
1 | S2
| S3
--------------
| S4
2 | S5
| S6
--------------
my angular code is:
<tr ng-repeat = "user in users">
<td>{{user.id}}</td>
<td>{{user.subject}}</td>
</tr>
my json object is :
user:[
{id:1 ,
subjects:[
{id:1 , name:"eng"}
{id:2 , name:"phy"}
]
},
{id:2 ,
subjects:[
{id:1 , name:"eng"}
{id:3 , name:"math"}
]
}
]
I want to generate html table 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>
how to insert multiple rows in one column using angular
Use ng-repeat-start and ng-repeat-end. For example:
<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>
Here is a full 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"
}, {
id: 4,
name: "hist"
},
{
id: 5,
name: "geog"
}]
}];
$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>
Also, working fiddle here: http://jsfiddle.net/donal/r51d5fw5/17/
An alternative version, using nested ng-repeat, can be implemented using a div to display the nested subject information:
<tr ng-repeat="user in users">
<td>{{user.id}}</td>
<td>
<div ng-repeat="subject in user.subjects">S{{subject.id}}</div>
</td>
</tr>
rowspan will do everything you need. Follow this link:
w3schools This is one of the best resources for web development.
Using div u can also do
<div ng-repeat = "user in users">
<div> {{user.id}} </div>
<div ng-repeat = "user1 in users.subjects">
{{user1.id}} : {{user1.name}}
<div>
</div>
Donal's answer is good.
But I edited to show beautiful table:
<table class="table table-bordered table-hover table-height m-b-xs">
<thead>
<tr>
<td>ID</td>
<td>Subjects</td>
<td>name</td>
</tr>
</thead>
<tbody>
<tr ng-repeat-start="user in users">
<td rowspan="{{user.subjects.length}}">key {{user.id}}</td>
<td>S{{ user.subjects[0].id }}</td>
<td>{{ user.subjects[0].name }}</td>
</tr>
<tr ng-repeat-end ng-repeat="subject in user.subjects.slice(1)">
<td>S{{subject.id}}</td>
<td>{{subject.name}}</td>
</tr>
</tbody>

I have a table built in Angular 8. I am not using Material UI.
I want to reorder the columns in the table using JSON. Is there any way that could be done?
My Angular table code is like below:
<table>
<thead class="thead-light">
<tr>
<th *ngFor="let data of tableHeaders">
{{ data.value }}
</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let data of transactions ">
<td>{{ data.firstName }}</td>
<td>{{ data.regNo }}</td>
<td>{{ data.course }}</td>
</tr>
</tbody>
</table>
My tableheader json:
this.tableHeaders = [
{
"id": 'first_name',
"value":"Name",
},
{
"id": 'reg_no',
"value":"Reg No"
},
{
"id": 'course_name',
"value":"Course"
},
]
While I am able to change the order of the table headers by setting an id and sorting the array - tableHeaders, but how do I do the same for the td?
Any help would be appreciated.
You need to modify header and content's key to make it relate together something like
Full example: Stackblitz
.ts
this.tableHeaders = [
{
"id": 'first_name',
"value":"Name",
"key": "firstName"
},
{
"id": 'reg_no',
"value":"Reg No",
"key":"regNo"
},
{
"id": 'course_name',
"value":"Course",
"key": "course"
},
]
.html
<table>
<thead class="thead-light">
<tr>
<th *ngFor="let data of tableHeaders">
{{ data.value }}
</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let data of transactions">
<td *ngFor="let header of tableHeaders">
{{ data[header.key] }}
</td>
</tr>
</tbody>
</table>
I have array like this
$scope.orderno=[
{"orderno":1254,"weight":25875,"group":5},
{"orderno":56787,"weight":25875,"group":5},
{"orderno":567,"weight":25875,"group":3},
{"orderno":123254,"weight":25875,"group":3}
];
now i want to show in html like below
I tried but i can't.I attached my tried code below.
<div ng-app>
<table ng-controller="MainCtrl">
<thead>
<div>
<tr>
<td>orderno</td>
<td>weight</td>
<td rowspan={{orderwt}}>group</td>
</tr>
</div>
</thead>
<tbody ng-repeat="item in orderno">
<tr>
<td></td>
<td></td>
<td rowspan="{{orderno.length}}">{{item.group}}</td>
</tr>
<tr>
<td>{{item.orderno}}</td>
<td>{{item.weight}}</td>
</tr>
</tbody>
</table>
</div>
i tried but i can't find correct answer
The first thing you should do is transform your data into a format that's easier to iterate over. For example, you could use array.reduce() to help you create a new object that's keyed by group number. Then you can iterate over this object to create your table.
See example snippet with comments below:
// This is your original data array
let arr = [{
"orderno": 1254,
"weight": 25875,
"group": 5
},
{
"orderno": 56787,
"weight": 25875,
"group": 5
},
{
"orderno": 567,
"weight": 25875,
"group": 3
},
{
"orderno": 123254,
"weight": 25875,
"group": 3
}
], // Use reduce and Object.create to make a new object keyed by group number
result = arr.reduce(function(r, a) {
r[a.group] = r[a.group] || [];
r[a.group].push(a);
return r;
}, Object.create(null));
let app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$scope.groups = result;
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<table border="1">
<thead>
<td>Group</td>
<td>Order No</td>
<td>Weight</td>
</thead>
<tbody ng-repeat="(key, value) in groups"> <!-- Outer loop -->
<tr ng-repeat="group in value"> <!-- Inner loop -->
<td ng-if="$index == 0" rowspan="{{ value.length }}">{{ group.group }}</td>
<!-- the above is so we only add the rowspan once -->
<td>{{ group.orderno }}</td>
<td>{{ group.weight }}</td>
</tr>
</tbody>
</table>
</div>
I have a simple Angular.js application that grabs tabular data from a mysql database and shows it in a simple bootstrap table. I’m using this code below to show the table column names without hardcoding them individually…
HTML:
<table class="table">
<thead>
<tr style="background:lightgrey">
<th ng-repeat="column in columns"> {{ column }} </th>
</tr>
</thead>
and in the controller I create ’$scope.columns’ with something like this…
var columnNames = function(dat) {
var columns = Object.keys(dat[0]).filter(function(key) {
if (dat[0].hasOwnProperty(key) && typeof key == 'string') {
return key;
}
});
return columns;
};
DataFactory.getTables(function(data) {
$scope.columns = columnNames(data);
$scope.tables = data;
});
And this works as expected and it’s great, but what about the the rest of the data.. So for example, the body of my table currently looks like this…
HTML:
<tbody>
<tr ng-repeat="x in tables ">
<td> {{ x.id}} </td>
<td> {{ x.name }} </td>
<td> {{ x.email }} </td>
<td> {{ x.company }} </td>
</tbody>
I’ve tried using two loops like this…
HTML:
<tbody>
<tr ng-repeat="x in tables">
<td ng-repeat=“column in columns”> {{ x.column }} </td>
</tr>
</tbody>
But this code doesn’t work, So is it possible to populate a table with angular without hardcoding the column names in HTML, and if so whats the most efficient way to do so?
You might want to try this https://jsfiddle.net/8w2sbs6L/.
<div data-ng-app="APP">
<table ng-controller="myController" border=1>
<thead>
<tr>
<td ng-repeat="column in columns">{{column}}</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in tables">
<td ng-repeat="column in columns">{{x[column]}}</td>
</tr>
</tbody>
</table>
</div>
<script>
'use strict';
angular.module('APP', [])
.controller('myController', ['$scope', function($scope){
$scope.tables = [
{
"column1":"row1-column1",
"column2":"row1-column2",
"column3":"row1-column3",
"column4":"row1-column4"
},
{
"column1":"row2-column1",
"column2":"row2-column2",
"column3":"row2-column3",
"column4":"row2-column4"
}
];
$scope.columns = [
"column1",
"column2",
"column3",
"column4"
];
}]);
</script>
I have nested ng-repeats like below :
<table class="table table-striped table-bordered" border=1>
<tbody ng-repeat="list in globalList">
<tr ng-repeat="child in list">
<td ng-repeat="baby in child">
{{baby.second}}
</td>
</tr>
</tbody>
</table>
What I'd like to have is a table as header the baby.title property and as data baby.second
Something that looks like to this :
|baby.title | baby.title | ... | ->HEADERS
--------------------------------
|baby.second| baby.second| ... |
|baby.second| baby.second| ... |
|baby.second| baby.second| ... | ->DATAS
My data structure in picture :
I don't know if that's possible with my data structure tho and I can hardly change it.
Any advices ?
UPDATE: Check this code. I added new variable in JS $scope.longestArray
var app = angular.module('app', []);
app.controller('ctrl', function($scope) {
$scope.globalList = [
[
[{
'second': "dataAA",
'title': "titleA"
}, {
'second': "dataAB",
'title': "titleA"
}]
],
[
[{
'second': "dataBA",
'title': "titleB"
}, {
'second': "dataBB",
'title': "titleB"
}, {
'second': "dataBC",
'title': "titleB"
}]
],
[
[{
'second': "dataCA",
'title': "titleC"
}]
]
];
$scope.longestArray = angular.copy($scope.globalList).sort(function(a, b) {
return b[0].length - a[0].length;
})[0][0];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app" ng-controller="ctrl">
<table>
<thead>
<tr>
<th ng-repeat="list in globalList">
{{list[0][0].title}}
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="baby in longestArray">
<td ng-repeat="list in globalList">
{{list[0][longestArray.indexOf(baby)].second}}
</td>
</tr>
</tbody>
</table>
</body>

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>

Similar to the nested structure of your object, you can nest your ng-repeats like this...
<tr ng-repeat = "user in users">
<td>{{user.id}}</td>
<td ng-repeat="subject in user.subjects">{{subject.name}}</td>
</tr>
I split your JSON and push it into two $scope variable, like the below:
angular.forEach($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 the HTML, I am using filter to filter by user's 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 of the way to achieve this.
Sample Plunker
Here, I'm assuming that you want each user in users (in your JSON object) in one table, so you can do something as follows:
<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 this is the basic idea :)
Hope this helps!
add users object in $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>
