You can use the autotable:

import autoTable from 'jspdf-autotable'

And in the method pdfHtml() and changue to:

    public pdfHtml() {
      alert(this.el.nativeElement.innerHTML);
        let pdf = new jsPDF();
        let options = {
            pagesplit: true
        };

    //Add this
    autoTable(pdf, {
      tableWidth: 'auto',
     // head: [['id', 'Name']],
     head: [['id', 'Name']],
     // body: [ [1, 'Superman', ],[2, 'Batman', ],[3, 'Batgirl', ] ],
     body: heroes ,
     },);
     

        pdf.addHTML(this.el.nativeElement, 0, 0, options, () => {
            pdf.save("test1.pdf");
        });
    }

Good Luck!
