I am currently facing a situation in which I have an HTML table connected to a Reactive Form's FormArray. The information retrieved from the server is displayed in the table and should always be read-only. However, I wish to allow the addition of a new row that is editable, with input fields and dropdowns.
Check out this Stackblitz example where I can add a new row, but it remains read-only. I would like the newly added row to contain editable input controls.
Is there a way to achieve this?
There are multiple approaches to accomplish this:
One option is to include the editable property in a new user object and then adjust your td rendering based on whether it is editable or not. Here is a pseudo code example:
<td *ngIf="!user.editable">{{user.name}}</td>
<td *ngIf="user.editable"><input matInput ... ></td>
Another approach is to utilize an editableIndex within your component. If the editableIndex is -1, nothing is editable. Otherwise, it represents the index of the editable row.
<td *ngIf="editableIndex!==i">{{user.name}}</td>
<td *ngIf="editableIndex===i"><input matInput ... ></td>
Instead of having two tds in the template, you can make your input readonly (or disabled for selects):
<td><input [readonly]="editableIndex!==i" matInput ... ></td>
