The PrimeNG table component is a powerful data visualization tool and is a great free alternative to AG Grid.
Table columns can be defined dynamically using the *ngFor directive. However, if you do this there is no apparent way to conditionally mark a column as editable!
There is actually an undocumented pEditableColumnDisabled boolean directive that can be used to control if a cell is editable or not. The only documented directives are pEditableColumn and pEditableColumnField.
Here is a direct link to the directive on the PrimeNG github.
Using it would be something like: <td pEditableColumn [pEditableColumnDisabled]="!col.editable" *ngFor="let col of columns" [ngSwitch]="col.field">
