Add / remove cols dynamically

[GaillardQ]

Hi, I am meeting a problem about adding/removing columns dynamically... I update the columns variable, but the cols are still displayed in the table....

Hey, If you are trying to update the columns at runtime then make sure that after updating columns you must call onChangeTableFunction

this.onChangeTable(this.config);

According to its functionality it will rerender html. It will works for you I hope

[ervbsankar]

Did you solve this?

[rsksmiles]

No - I replaced it with ngPrime data table.

Dummy workarond:

    <div *ngIf="columns.length == 9">
      <ng-table [config]="config"
                ...
                [columns]="columns"
                [totals]="totals"
                [pageTotals]="pageTotals">
      </ng-table>
    </div>
    <div *ngIf="columns.length != 9">
      <ng-table [config]="config"
                ...
                [columns]="columns"
                [totals]="totals"
                [pageTotals]="pageTotals">
      </ng-table>
    </div>

Or you can use whatever boolean you need
