I have created dynamic column in typescript html.

I have declared a variable public totallist:any

and initialised it by this.totallist=new Array();

  <div  *ngFor="let number of  columnnumberArray;let n= index " >

    <ngx-datatable-column name="{{number}}" [width]="50">

         <ng-template ngx-datatable-cell-template let-row="row" let-value="value">{{row.$$index}} {{n }} 

    {{this.totallist[[n][row.$$index]]}}

   <input  type="text"  [(ngModel)]="this.totallist[row.$$index][n]"  (ngModelChange)="listen();"  id="Samplesize" name="Samplesize" 

    class="form-control" >

         </ng-template>

         </ngx-datatable-column>

          </div >

But when I add values.model values are overridden.

expected output(if two columns are created then )

[0][1:"hi",2:"hello"] 

[1][1:"hi1",2:"hello2"] 

[2][1:"hi3",2:"hello4"] 

[3][1:"hi5",2:"hello5"] 

component code[this will create dynamic array]

 createrow() {

    this.columnnumberArray = new Array();

    console.log("this.columnnumber", this.columnnumber)

    for (let i = 1; i <= this.columnnumber; i++) {

      this.columnnumberArray.push(i);



    }



  }
