I have an array which contains other arrays inside like that:
array = [
["element A", "element B"],
["YES", "NO"]
]
And I want to loop through this array of object in an HTML table using ngFor:
<table>
<thead>
<tr>
<th>#</th>
<th>COLUMN 1</th>
<th>COLUMN 2</th>
</tr>
</thead>
<tbody>
<template *ngFor="let row of csvContent; let in = index">
<th scope="row">{{in}}</th>
<template *ngFor="let c of row; let in = index">
<td>
{{c[0]}}
</td>
</template>
</template>
</tbody>
</table>
I want to display each inner array list below COLUMN1 and COLUMN2 respectively:
COLUMN1 | COLUMN2
--------------------
element A | YES
element B | NO
I can't figure it out how to use *ngFor properly in order to list an array of arrays (Simple list of strings). At the moment, it's either an empty array or a shifted & messed up Table presentation.
This is how looks the Table:
Or this wrong presentation because Element A and B should be below COLUMN 1 and YES, NO should be below COLUMN2:
Your data is not arrays in arrays; it's two connected arrays. You need to treat it as such:
<tbody>
<tr *ngFor="let column of csvContent[0]; let in = index">
<td>
{{csvContent[0][in]}}
</td>
<td>
{{csvContent[1][in]}}
</td>
</tr>
</tbody>
This is not really a good way of organizing your data, as stuff is not really related. What if csvContent[0] gets a new entry, but 1 doesn't? Right now, your data doesn't represent a table, and I'd recommend transforming it in your controller to be tabluar, and then printing.
Try this:
<table>
<thead>
<tr>
<th>#</th>
<th>COLUMN 1</th>
<th>COLUMN 2</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let row of csvContent;let i = index;">
<td>{{i}}</td>
<td *ngFor="let c of row">
{{c}}
</td>
</tr>
</tbody>
</table>
I wasn't sure how your data looked like, but seems like this would help.
You don't really need to use <template> tags (they're deprecated anyway in favor of <ng-template> tags.
Also, no need for index tracking if you're gonna access the array at that index anyway.
Simply loop like this
<table>
<thead>
<tr>
<th>#</th>
<th>COLUMN 1</th>
<th>COLUMN 2</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let row of csvContent;let i = index;">
<td>{{i}}</td>
<td *ngFor="let c of row">{{c}}</td>
</tr>
</tbody>
</table>

I'm trying to hide whole column with all elements in that column when the checkbox is clicked. I'm wondering what's the best approach to solve that using Angular.
<table class="table">
<thead>
<tr>
<th scope="col">Name</th>
<th scope="col">Email</th>
<th scope="col">Date</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let user of Items" >
<td>{{user.Name}}</td>
<td>{{user.Email}}</td>
<td>{{user.Date}}</td>
</tr>
</tbody>
</table>
Above the table I have 3 checkboxes:
Name | Email | Date
I want to press one of them and then whole column disappears including <th> element and <td> element.
What could be the best idea for this problem?
To hide columns when a checkbox is selected.
In your .ts create 3 variables set to true for each column.
showName = true;
showEmail = true;
showDate = true;
in your respective checkboxes you need to add checked and change calls for each and match it to the 3 booleans above:
<input type="checkbox" [checked]="!showName" (change)="showName=!showName"/>
<input type="checkbox" [checked]="!showEmail" (change)="showEmail=!showEmail"/>
<input type="checkbox" [checked]="!showDate " (change)="showDate =!showDate "/>
And then add *ngIf in each related th and td for example for the name td and th:
<th scope="col" *ngIf="showName">Name</th>
<td *ngIf="showName">{{user.Name}}</td>
declare class
export class ColumnVisible{
public nameVisible:boolean=true;
public emailVisible:boolean=true;
public dateVisible:boolean=true;
constructor(){}
}
call it in component
columnVisible:ColumnVisible;
in costructor initialize it with
this.columnVisible=new ColumnVisible();
inhtml write as class and give click event
<input [(ngModel)]="columnVisible.nameVisible" type="checkbox"(change)="columnVisible.nameVisible=!columnVisible.nameVisible" />
<input [(ngModel)]="columnVisible.emailVisible" type="checkbox"(change)="columnVisible.emailVisible=!columnVisible.emailVisible" />
<input [(ngModel)]="columnVisible.dateVisible" type="checkbox"(change)="columnVisible.dateVisible=!columnVisible.dateVisible" />
<table class="table">
<thead>
<tr>
<th ngIf="columnVisible.nameVisible" scope="col">Name</th>
<th ngIf="columnVisible.emailVisible" scope="col">Email</th>
<th ngIf="columnVisible.dateVisible" scope="col">Date</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let user of Items" class="{{user.IsShown}}" >
<td ngIf="columnVisible.nameVisible" >{{user.Name}}</td>
<td ngIf="columnVisible.emailVisible">{{user.Email}}</td>
<td ngIf="columnVisible.dateVisible">{{user.Date}}</td>
</tr>
</tbody>
</table>
Here's a little bit of code. stackblitz. You just need three different models for different checkboxes or use 1 property but with different types
I want to make a hierarchical data table with angularjs.
For example, it can lower the table and took a table in the first row of the table.
How can I create nested tables this event ?
I wrote how I wanted to do something as an example below.
Please hepl me! Thank you.
Example:
<table>
<thead>
<tr>
<th>Head 1</th>
</tr>
</thead>
<tbody>
<tr>
<td>Content 1</td>
</tr>
<tr>
<td style="margin-left: 10px">
<table>
<thead>
<tr>
<th>Head 1.1</th>
</tr>
</thead>
<tbody>
<tr>
<td>Content 1.1</td>
</tr>
<table>
<thead>
<tr>
<th></th>
</thead>
<tbody>
<tr>
<td>Content 1.1.1</td>
</tr>
</tbody>
</table>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
First of all - Table in Tables is valid html (see: Is a html table within a table valid?)
Second of all - What is the real question here? You need a controller storing the data you want to display. You can iterate with ng-repeat to get the structure.
It looks like you want to display a Table of Contents. A list is a better option here:
HTML:
<div ng-controller="TableController">
<ul>
<li ng-repeat="c in content">
{{c.header}}
<ul>
<li ng-repeat="cc in c.content">{{cc}}</li>
</ul>
</li>
</ul>
</div>
Controller:
var app = angular.module("tableApp", []);
app.controller("TableController", ["$scope",function($scope){
$scope.content = [
{ header: "Head 1", content: ["Content 1"]},
{ header: "Head 1.1", content: ["Content 1.1", "Content 1.1.1"]}
];
}]);
// See: https://jsfiddle.net/6se8xq41/
see example here
Essentially I need to add a little button or something within the headers of the table to be able to sort the data alphabetically by column. I've been having trouble with doing this making use of AngularJS and need some help with it.
This is a snippet showing the table and...
<div class="col-md-10">
<table class="table table-hover table-bordered">
<thead>
<tr>
<th>Status</th>
<th>Ref</th>
<th>Service</th>
<th>Domain</th>
<th>Service Owner</th>
<th>Stage</th>
</tr>
</thead>
<tbody>
<tr ng-click="isCollapsed = !isCollapsed" ng-repeat-start="x in projects | filter:query | filter:myFilter | orderBy:orderProp">
<td><b>{{x.a}}</b></td>
<td>{{x.b}}</td>
<td><u>{{x.c}}</u></td>
<td>{{x.d}}</td>
<td>{{x.e}}</td>
<td>{{x.f}}</td>
</tr>
<tr collapse="isCollapsed" ng-repeat-end="">
<td colspan="6">
<h3>Test</h3>
<p>Test</p>
</td>
</tr>
</tbody>
</table>
</div>
</div>
This is a plnkr of the code http://plnkr.co/edit/OkRbR9geeOcCGy2K01jB?p=preview
Give this a try for a very simple solution:
HTML:
<table>
<thead>
<tr>
<th>Status<a ng-click="orderProperty = 'a'">^</a></th>
<th>Ref<a ng-click="orderProperty = 'b'">^</a></th>
<th>Service<a ng-click="orderProperty = 'c'">^</a></th>
<th>Domain<a ng-click="orderProperty = 'd'">^</a></th>
<th>Service Owner<a ng-click="orderProperty = 'e'">^</a></th>
<th>Stage<a ng-click="orderProperty = 'f'">^</a></th>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in projects | orderBy:orderProperty">
<td><b>{{x.a}}</b></td>
<td>{{x.b}}</td>
<td>{{x.c}}</td>
<td>{{x.d}}</td>
<td>{{x.e}}</td>
<td>{{x.f}}</td>
</tr>
</tbody>
</table>
JavaScript:
app.controller('controller', function($scope) {
$scope.orderProperty = "f"; // Sort by "f" by default
$scope.projects = [...];
});

Is it possible to make a tablecolumn editable when using angularjs? I have this table:
<table>
<thead>
<tr class="header">
<th>id</th>
<th>files</th>
</tr>
</thead>
<tbody ng-repeat="person in persons">
<tr>
<td>{{person.id}}</td>
<td>{{person.fileNames)}}</td>
</tr>
</tbody>
</table>
So I have a $scope.fileNames which is an array containing filenames per person for example:
["Koala.jpg","Tulips.jpg","Tulips.jpg","Hydrangeas.jpg","Lighthouse.jpg","Chrysanthemum.jpg"]
I would like to make this 2nd column editable for the user so he can change/delete the files how can I accomplish this?
Use contentEditable
<table>
<thead>
<tr class="header">
<th>id</th>
<th>files</th>
</tr>
</thead>
<tbody ng-repeat="person in persons">
<tr>
<td contentEditable>{{person.id}}</td>
<td contentEditable>{{person.fileNames)}}</td>
</tr>
</tbody>
</table>
I'm stuck in getting parent ng-repeat value using child ng-repeat slug. It shows nothing just blank td's
What I've done
$scope.column = [column_id: "12"slug: "item6"sort: "0"status: "1"title: "Contact no"ts_datetime: "2014-12-12 12:27:50"];
$scope.column.item = [item1: "1"item2: "2"item3: "3"item4: "4"item5: "5"item6: "8"item_id: "1"status: "1"]
<table class="table table-bordered table-striped">
<thead>
<tr>
<th ng-repeat="column in columns" >{{ column.title }}</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in listings">
<td ng-repeat="column in columns" ng-init="val = item.column.slug">{{ val }}</td>
</tr>
</tbody>
</table>
What I want is this. to get the value of item with the slug of column. Like item.column.slug
It looks like you want to use:
<td ng-repeat="column in columns">{{item[column].slug}}</td>
