How to create a link using other column id?

angular
1

Hi,

I am fetching data using http.get.

and getting two values

buy_report and buy_report_link.

I want to show buy_report as a href with value buy_report_link in my ag-grid?
But using cellrender

{
headerName:"Buy Report",
field:"buy_report",
width:120,
cellStyle: { 'text-align': "left" },
cellRenderer: function(params) {
return '<a href="http://local.com//'+params.value.toLowerCase()+'" target="\_blank">'+ params.value+'</a>'
}
},

onGridReady(params){
    this.gridApi = params.api;
    this.gridColumnApi = params.columnApi;

    this.http.get("http://local.com/past-recommendations")
    .subscribe(data=>{
      this.rowData = data as any;        
    });

here I can use same column value but

I want to use other column vauue(buy_report_link).
Any idea how I can achieve this?

thanks
