如何在jspdf angular8中显示嵌套的Json

import * as jspdf from 'jspdf';
import 'jspdf-autotable';

generatePDF() {
  const doc = new jspdf();
  const data = [
    { id: 1, name: 'John Doe', age: 30, address: { city: 'New York', country: 'USA' } },
    { id: 2, name: 'Jane Smith', age: 25, address: { city: 'London', country: 'UK' } },
    // Add more data as needed
  ];

  const columns = ['ID', 'Name', 'Age', 'City', 'Country'];
  const rows = [];

  data.forEach(item => {
    const temp = [item.id, item.name, item.age, item.address.city, item.address.country];
    rows.push(temp);
  });

  doc.autoTable(columns, rows);
  doc.save('nested-json.pdf');
}

<button (click)="generatePDF()">Generate PDF</button>
