      <table>  
        <thead>  
          <tr>  
            <th>Header 1</th>  
            <th>Header 2</th>  
            <th>Header 3</th>  
          </tr>  
        </thead>  
        <tbody>  
          <tr>  
            <td>Row 1, Cell 1</td>  
            <td>Row 1, Cell 2</td>  
            <td>Row 1, Cell 3</td>  
          </tr>  
          <tr>  
            <td>Row 2, Cell 1</td>  
            <td>Row 2, Cell 2</td>  
            <td>Row 2, Cell 3</td>  
          </tr>  
          <!-- Add more rows as needed -->  
        </tbody>  
      </table>  
    </div>  
    <button @click="exportToPDF">Export to PDF</button>  
  </div>  
</template>  

<script>  
import jsPDF from 'jspdf';  
import html2canvas from 'html2canvas';  

export default {  
  name: 'TableToPDF',  
  methods: {  
    async exportToPDF() {  
      const tableContainer = document.getElementById('table-container');  
      const canvas = await html2canvas(tableContainer);  
      const imgData = canvas.toDataURL('image/png');  

      const pdf = new jsPDF('p', 'mm', 'a4');  
      const imgWidth = 190; // Adjust width according to your table width  
      const imgHeight = (canvas.height * imgWidth) / canvas.width;  

      pdf.addImage(imgData, 'PNG', 10, 10, imgWidth, imgHeight);  
      pdf.save('table.pdf');  
    },  
  },  
};  
</script>  

<style scoped>  
#table-container {
