What would be the best way to dynamically add an HTML element, such as another column onto a basic HTML table?
I want to have a button below the table, and if the user were to click the button, the event would add the same amount of rows already in the table and add another column. I would want to support about 5 extra columns being added to the table.
Here's my HTML table as of right now:
<table>
<thead>
<tr>
<th id="row-tag"></th>
<th id="option-column">Option 1</th>
</tr>
</thead>
<tbody>
<tr>
<td id="row-tag">P</td>
<td id="option-column">{{ p }}</td>
</tr>
<tr id="row-tag">
<td>
<app-a-p (saveButtonClick)="toggleAP($event)"
[modModalValues]="modModalValues">
</app-a-p>
</td>
<td id="option-column">
<div class="input-group input-group-sm">
$<input
*ngIf="toggleAP==true"
type="text"
name="aP"
size="10"
disabled
value=""
/>
<input
*ngIf="toggleAP==false"
type="text"
name="aP"
size="10"
[ngModel]="con.pA"
(ngModelChange)="con.pA = $event" appFormatP
(blur)="checkAP($event.target.value);
inputTracker.addModifiedValue('Option 1', $event.target.value)"
/>
</div>
</td>
</tr>
<tr>
<td id="row-tag">L</td>
<td id="option-column">${{l}}</td>
</tr>
<tr>
<td id="row-tag">R</td>
<td id="option-column">${{r}}</td>
</tr>
</tbody>
</table>
I think in Angular, you define table based on your data. for example, you have fields array defining columns, and data array defines the what's actually in the table.
<table >
<thead>
<tr>
<th *ngFor='let key of this.fields'>{{key}}</th>
</tr>
</thead>
<tbody>
<tr *ngFor='let row of this.data ' >
<td scope="row" *ngFor='let key of this.fields'> {{row[key]}} </td>
</tr>
</tbody>
</table>
when you need a new column, just push a new field into fields. like
fields.push('newcolumn');
when you need a new row, just do:
data.push({col1: '', col2:'', newcolumn: ''});
Look into the insertRow() and insertCell() functions in JavaScript. This alongside an onClick function that you write will let you edit the table.
A good way of generating a table on UI when using angular would be to use 2D-array (row*column) use can have a button using which you can dynamically add values to this array and have another row/column to the table.

I want to create a table that its data is a Map< String, List < Object> >.
So the table has one header that and the rows should have the exact data.
Map.key
Object.item1
Object.item2
Object.item3
So since it is a List of Object i want one row for every Object of the List and the Map.key to be repeated.
So i need to iterate through keys like
<table>
<thead>
<tr>
<th>Code</th>
<th>Status</th>
<th>Flag</th>
<th>Message</th>
</tr>
</thead>
<tbody>
<tr th:each= "result : ${myMap}">
<td th:text="${result.key}"></td>
<td><table>
<tr th:each="obj: ${result.value}">
<td th:text="${not #lists.isEmpty(obj.errorList)}?'Error':'Warning'"></td>
<td th:text="${obj.flag}==true?'YES':'NO'"></td>
<td th:text="${not #lists.isEmpty(obj.errorList)}?${obj.warningList}:${obj.errorList}"></td>
</tr>
</table></td>
</tr>
</tbody>
</table>
but this solution places a table in a table. I want to use one header and iterate the lists and place the variables in the main table .
I think you're looking for a structure like this:
<table>
<thead>
<tr>
<th>Code</th>
<th>Status</th>
<th>Flag</th>
<th>Message</th>
</tr>
</thead>
<tbody>
<th:block th:each= "result : ${myMap}">
<tr th:each="obj: ${result.value}">
<td th:text="${result.key}" />
<td th:text="${not #lists.isEmpty(obj.errorList)}?'Error':'Warning'" />
<td th:text="${obj.flag}==true?'YES':'NO'" />
<td th:text="${not #lists.isEmpty(obj.errorList)}?${obj.warningList}:${obj.errorList}" />
</tr>
</th:block>
</tbody>
</table>
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>
Seems to be the same requirement like AngularJS "Vertical" ng-repeat but solution doesn't work for *ngFor
I have this object array that I am trying to bind to an HTML table. Its format is something like below:
[
{
"Animal":"Dog",
"Country":"France",
"Food":"Tofu",
"Car":"Nano",
"Language":"TypeScript"
}
]
Now this can simply be formatted in the default HTML horizontal table way like this:
<table>
<tr>
<th>Animal</th>
<th>Country</th>
<th>Food</th>
<th>Car</th>
<th>Language</th>
</tr>
<tr *ngFor="let data of datas">
<td>{{data.Animal}}</td>
<td>{{data.Country}}</td>
<td>{{data.Food}}</td>
<td>{{data.Car}}</td>
<td>{{data.Language}}</td>
</tr>
</table>
This would create table like below(Please ignore the data in the table;its just to give an idea.):
But how would I create a structure like this with dynamic data(kind of a vertical table):
In Component:
this.arrayOfKeys = Object.keys(this.datas[0]);
html:
<table>
<tr *ngFor="let key of arrayOfKeys">
<th>{{key}}</th>
<td *ngFor="let data of datas">
{{data[key]}}
</td>
</tr>
</table>
Use ng-container if You have data structure similar to groups[].items[].name
So, if You want to add row
<table>
<ng-container *ngFor="let group of groups">
<tr>
<td>{{group.name}}</td>
</tr>
<tr *ngFor="let item of group.items">
<td>{{item.name}}</td>
</tr>
</ng-container>
</table>

I have one table, in this table two columns and 5 rows are there. In First column have a check box and second column have a data. I want get the second column row value of checked items.
My table id was "tb1", checkbox id "cb1" and second field id "da1".
I want the result like "Data2 and Data5" That means whatever I check, that particular second column(<td>) value.
This is possible, please help me.
If you are using cb2 and da2 for row two, then in javascript you could do:
If data column is td element only:
document.getElementById("da2").innerText
If data column is input element:
document.getElementById("da2").value;
JS Bin
Bind the event on every checkbox and the find second field" with the help of closest
JavaScript
$(function(){
$("#tb1").on('click','input',function(){
var value =($(this).closest('tr').find('[id^=da]').text())
alert(value)
})
})
HTML
<table id="tb1" cellpadding="5" border="1" cellspacing='0' width="200">
<tr>
<td id="cb1"><input type='checkbox' /> </td>
<td id="da1">Data 1</td>
</tr>
<tr>
<td id="cb2"><input type='checkbox' /> </td>
<td id="da2">Data 2</td>
</tr>
<tr>
<td id="cb3"><input type='checkbox' /> </td>
<td id="da3">Data 3</td>
</tr>
<tr>
<td id="cb4"><input type='checkbox' /> </td>
<td id="da4">Data 4</td>
</tr>
</table>
I'm really new at using Razor with MVC, and so far I really like it.
One little thing I want to do is write a variables value to an attribute in HTML.
For example, if I had the following:
<table style="width: 100%">
<tr>
<th>
ID
</th>
<th>
Name
</th>
<th>
Value
</th>
</tr>
#foreach (var item in Model)
{
<tr id="ID#item.id">
<td>
#item.id
</td>
<td>
#item.name
</td>
<td>
#item.value
</td>
<td>
</tr>
}
</table>
I would want all the tags to have an ID equal to "ID[insert item's id]", but instead I get an ID equal to "ID#item.id".
How do I write a variable's name between HTML quote marks?
Thanks!
This pattern is recognized as an email address. Do the following to work around this behavior:
<tr id="ID#(item.id)">
