I built the following stackblitz example
https://stackblitz.com/edit/angular-y454qb?file=src%2Fapp%2Ftable-header%2Ftable-header.component.css
As you can see I have parent table table which has one child component called table-header
If I write this code directly in my table component then my th colspan attribute will get applied
and will get the whole width of the table
<thead>
<th class="tableHeader" colspan="12">my table header</th>
</thead>
but if I put the same code inside nested component - in my casetable-header
then the code does not work and the colspan attribute does not get applied to the table and does not get the full width of the table.
How can I fix this?
The problem is how the app-table-header component is rendered by Angular. If you look at the result of the table being rendered you will see something like....
result of original table render
<table>
<thead>
<th class="tableHeader" colspan="12">my table header</th>
</thead>
<app-table-header>
<thead>
<th colspan="12">my table header</th>
</thead>
</app-table-header>
</table>
When app-table-header rendered there is an extra element between the <table> and the <thead> which breaks the table.
A possible solution is to make app-table-header an attribute selector, [app-table-header] and use a thead in your table with the attribute selector <thead app-table-header>.
table-header.compnonent.ts
#Component({
selector: 'thead[app-table-header]',
templateUrl: './table-header.component.html',
styleUrls: ['./table-header.component.css']
})
export class TableHeaderComponent implements {
#Input()
public heading: string = '';
}
table-header.component.html
<!-- Remove the thead from here -->
<th class="tableHeader" colspan="12">{{ heading }}</th>
table.component.html
<table>
<thead>
<th class="tableHeader" colspan="12">my table header</th>
</thead>
<thead app-table-header heading="Passing heading down with #Input"></thead>
</table>
This will result in the below html
<table>
<thead>
<th class="tableHeader" colspan="12">my table header</th>
</thead>
<thead app-table-header>
<th colspan="12">Passing heading down with #Input</th>
</thead>
</table>
See stackblitz below

EDIT
Updated the selector to thead[app-table-header] as suggested by #
Mazedul Islam.
Added #Input() to show you can pass values down with inputs.

I want display cricket team details. First row of a table is the captains, so for every first row color, I want to make the font size to be green and bold
This is My HTML:
<div >
<table id="sports" border=1 align=center >
<thead >
<tr>
<th>Team1</th>
<th>Team2</th>
</tr>
</thead>
<tbody *ngFor="let T of Teams" >
<td> {{T.Indian_players}}</td>
<td>{{T.Australia_players}}</td>
</tr>
</tbody>
</table>
</div>
This is my model, where I have taken static data:
export const Players=[
{Indian_players:'Kohili(c)',Australia_players:'David Warner(c)',Pakistan_players:'shaheen Afridi(c)',Southafrica_players:'dale steyn(c)',England_players:'Harry Kane(c)'},
{Indian_players:' Dhoni',Australia_players:'Steve Smith',Pakistan_players:'sarfraz Ahmed',Southafrica_players:'du plessis',England_players:'Joe Root'},
{Indian_players:'Rohit Sharma',Australia_players:'Glen Maxwell',Pakistan_players:'Babar Azam',Southafrica_players:'Imran Tahir',England_players:'Alex Hales'},
{Indian_players:'Jadeja',Australia_players:'Aron Finch',Pakistan_players:'Mohamad Hafeez',Southafrica_players:'David Miller',England_players:'James Anderson'},
{Indian_players:'K.L.Rahul',Australia_players:'Mitchel Starc',Pakistan_players:'Imad Wasim',Southafrica_players:'Jp duminy',England_players:'Moeen Ali'},
{Indian_players:'Bhuvaneswar Kumar',Australia_players:'Travis Head',Pakistan_players:'Shadab khan',Southafrica_players:'de kock',England_players:'Jos Buttler'},
{Indian_players:'Shikar Dhawan',Australia_players:'Pat cummins',Pakistan_players:'yasir shah',Southafrica_players:'Hashim Amla',England_players:'Ben Strokes'},
{Indian_players:'RishabPanth',Australia_players:'Mitchel Marsh',Pakistan_players:'Imam-ul-haq',Southafrica_players:'chris morris',England_players:'Sam Billings'},
{Indian_players:'Ashwin',Australia_players:'Peter siddle',Pakistan_players:'Faheem Ashraf',Southafrica_players:'Aiden markram',England_players:'Eoin Morgan'},
{Indian_players:'Dinesh Karthik',Australia_players:'Tim Paine',Pakistan_players:'Shoib Malik',Southafrica_players:'Dean Elgar',England_players:'chris Woakes'},
You can do the following.
<tbody>
<tr *ngFor="let T of Teams; let i = index" [class.your-captain-css-class]="index===0">
<td> {{T.Indian_players}}</td>
<td>{{T.Australia_players}}</td>
</tr>
</tbody>
I've done the following.
getting the index along with object.
Adding class if index is 0.
This is cover your requirement. There is another way of doing it only by CSS.
You can do it with CSS by doing this
custom-class:first-child {
color: yellow;
font-size: 15px;
}
Also, you have an error in your sample an ending tr tag but no beginning tr tag inside the body
<tbody *ngFor="let T of Teams" >
<td> {{T.Indian_players}}</td>
<td>{{T.Australia_players}}</td>
</tr>
</tbody>
I believe after reading the comments you could/should do this instead and use the CSS at the top and it should all work the reason I suggest using the class instead of tr is because if you are using tr you have used tr more then once and it will affect all tr tags instead of just the one you want in the body.
<tbody>
<tr *ngFor="let T of Teams" class="custom-class">
<td> {{T.Indian_players}}</td>
<td>{{T.Australia_players}}</td>
</tr>
</tbody>
So, my problem is so basic but i cant solve it.
I'm trying to create dynamic table header with *ngFor.
<table>
<tr>
<th>Entry Warehouse</th>
<th colspan="2" *ngFor="let data of datas">
SomeText
</th>
</tr>
<tr>
<th>More Text</th>
<div *ngFor="let data of datas">
<th>A little text again</th>
<th>A little text again</th>
</div>
</tr>
</table>
Anyway, this solution suicide themself at that point. If datas length more than 1, div tag is underscoring th tag in same cell.
If i try another solution like this;
<table>
<tr>
<th>Entry Warehouse</th>
<th colspan="2" *ngFor="let data of datas">
SomeText
</th>
</tr>
<tr>
<th>More Text</th>
<th *ngFor="let data of datas">A little text again</th>
<th *ngFor="let data of datas">A little text again</th>
</tr>
</table>
it looks like works but actually not. Because at this time the next th tag doesnt start before the previous loop ends.
In angular 2+ you can use<ng-container> tags
<ng-conatiner *ngFor="let i of items">
<th>i</th>
</ng-conatiner>
I'm trying to align the html table correctly but it comes off. The challenge that I have is with respect to the inner loop (modification) which is a list inside of Revision (in other words Revision 'has a' modification list.
While the result on screen are correct, the table is completely off. I speculate the problem is in the 2 *ngFor loop. Any pointer?
<table class="table table-striped">
<thead>
<tr>
<th>Revision No</th>
<th>Date</th>
<th>Username</th>
<th>Field</th>
<th>Old Value</th>
<th>New Value</th>
</tr>
</thead>
<tbody>
<tr>
<div *ngFor="let r of revisions">
<div *ngFor="let m of r.modifications">
<td>{{r.revision}}</a></td>
<td>{{r.date}}</td>
<td>{{r.username}}</td>
<td>{{m.forItem}}<td>
<td>{{m.oldInfo}}<td>
<td>{{m.newInfo}}</td>
</div>
</div>
</tr>
</tbody>
</table>
Nothing can go between your tr and td. Put the first ngfor in a tbody wrapped around your tr. Then put your second ngfor on the tr
You can't have a <div> at that position inside a table
Use
<ng-container *ngFor="let r of revisions">
instead of
<div *ngFor="let r of revisions">
Something I've recently discovered is that I can set a table cell to have multiple axises using a combination of the headers property on the td and the axis property on any related th. Example:
<table>
<caption>Country Toy Codes</caption>
<thead>
<tr>
<th scope="col row"></th>
<th scope="col" id="us" axis="country">US</th>
<th scope="col" id="ca" axis="country">CA</th>
<th scope="col" id="uk" axis="country">UK</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row" id="robots" axis="toys">Robots</th>
<td headers="us robots">ABC</td>
<td headers="ca robots">DEF</td>
<td headers="uk robots">GHI</td>
</tr>
<tr>
<th scope="row" id="dolls" axis="toys">Dolls</th>
<td headers="us dolls">JKL</td>
<td headers="ca dolls">MNO</td>
<td headers="uk dolls">PQR</td>
</tr>
<tr>
<th scope="row" id="slinkys" axis="toys">Slinkys</th>
<td headers="us slinkys">STU</td>
<td headers="ca slinkys">VWX</td>
<td headers="uk slinkys">YZ1</td>
</tr>
<tr>
<th scope="row" id="legos" axis="toys">Legos</th>
<td headers="us legos">AB1</td>
<td headers="ca legos">CD1</td>
<td headers="uk legos">EF1</td>
</tr>
</tbody>
</table>
This has clear benefits for non-visual browsers, but I was thinking it could also be useful for javascript and css. The only problem is that I'm not seeing a way to directly access the axis type of the header id of the cell, either after selecting or for selection purpose.
Ideally, I would like to do either of the following (rough pseduo-code ahead):
Selector:
td['axis=toys'] // Would select all td's with a header id that resolves to a header having axis value "toys"
Getter:
$('td').axisValue("toys") // would return the value, if applicable, of header id of header value with axis value of toys.
For the getter, I could loop through each header each time and find the element from the id in the DOM and then the axis value, but if there is a way to do this more directly, I'm sure it's also more optimized by the browser.
For the selector, the closest I can think of (in js) is to take the given axis value, find all ids using that axis value and then comma-separate each option to grab them all, such as
[headers~=us], [headers~=ca], [headers~=uk]
Does anyone know if header id's axis name is available either via a method or directly on the td element?
