I'm filling a pivot table with an array, but I can't add the delete button in another column of the table

my arrangement

const response =  [
   "elemento1",
   "elemento2"];

So I fill the table

 load("files", function (response) {
    
            var botones = document.getElementsByClassName('eliminaFile');
        
            multipleFileUploadError.style.display = "none";
            var content = "<p>Archivos Cargados: </p>";
        
        
            response.forEach((file, index) => rollCall(file, index));
        
            response.sort();
        
            let table = document.getElementById("tabla");
        //aquí recorro mi arreglo
            for (var i = 0; i < response.length; i++) {

        //aquí lleno la primer columna
                table.innerHTML += "<tr><td><a href='" + response[i] + "' target='_blank'>" response[i]+ "</a></td></tr>";
        
//aqui intento crear la otra columna con el botón eliminar
        // content += "<p>Descargar Archivo : <a href='" + response[i] + "' target='_blank'>" + response[i] + "</a></p>" + "<input class='eliminaFile' type='button' id='" + response[i] + "' value='Eliminar'>";
    
            }
            multipleFileUploadSuccess.innerHTML = content;
            multipleFileUploadSuccess.style.display = "block";
        });

this is the html of the table

<table class="demo">
                <thead>
                    <tr>
                        <th>Archivo</th>
                        <th>Acciones</th>
                    </tr>
                </thead>
                <tbody id="cuerpoTabla">
                </tbody>
            </table>

Several urls arrive in an array from which I want to extract the last part

http://130.10.1:8087/tests/downloadFile/file.txt

so far I have only managed to get what goes before the file name, but what I want is to only get the name of said files file.txt

var url = "http://130.10.1:8087/pruebas/downloadFile/archivo.txt";

var ultimaPosicion = url.lastIndexOf('/');
var nivelAnterior = url.substr(0, ultimaPosicion);
console.log(nivelAnterior);

I'm new to JS, can you help me please?

this is my div

<div id="print-section">

                        <div id="goqrcode"
                            style=" width:200px;   margin-left: auto; margin-right: auto; display: block;">
                            <h3 >{{nombre}} | {{item}}</h3></div>
                            
                    </div>

and so is my js

    let vacio: string = null;
    let printContents, popupWin;
    printContents = document.getElementById('print-section').innerHTML;
    popupWin = window.open('', '_blank', 'top=50%,left=0,height=100%,width=auto');
    popupWin.document.open();
    popupWin.document.write(`
      <html>
        <head>
          <title></title>
          <style>
          .content {
            height: 100vh;
            width: 100%;
            display: flex;
            flex-direction: column;
          }

          .img-content {
            flex: 1;
            display: flex;
            justify-content: center;
            align-items: center;
          }

          .observation {
            height: 150px;
            overflow: hidden;
            overflow-y: auto;
          }
          </style>
        </head>
    <body onload="window.print();window.close()">${printContents}</body>
      </html>`
    );
    popupWin.document.close();
  }

I receive the following json:

{
    "id": "7654321212",
    "lugar": "1",
    "procedencia": "E",
    "estado": "3",
    "fecha": "20210421",
    "hora": "010821",
    "series": [
        {
            "pin": "000000",
            "status": "2"
        },
        {
            "pin": "00300",
            "status": "1"
        }}

In Angular I receive it in the following way, my model:

export class Muestras {

    id: string;
    lugar: string;
    procedencia: string;
    estado: string;
    fecha: string;
    hora: string;
    series: string;
}

In the onInit:

muestras: Muestras[];

this.muestra.getMuestras().subscribe(e => {
    this.embarques = e;

If the values ​​are printed as the id, but I can't extract the value from the series array, it can only be done from the html or it has to be from typescript.
