Answer 1

Solved..

I have solved using css display:none;

<p-column *ngFor="let col of cols;let j=index;" 
[style]="{'width':'130px','display': col.display}" <<--add condition
[field]="col.field" 
[header]="col.header"

.ts

getColumns() {
    let ColumnNamePath = './assets/Grid Column Names/Oats-Exception-Summary-Columns.json';
    this.SharedHttpClientService.getJson(ColumnNamePath)
      .subscribe(column => {
        this.columnJson = [];
        for (var i = 0; i < column.length; i++) {

          this.cols[i] =
            { header: column[i].UI_ColumnName, field: column[i].MappingKey, datatype: column[i].DataType, label: column[i].UI_ColumnName, value: column[i].DB_ColumnName ,display: column[i].Display}
        }

      }, error => console.log(error));

}
