Generate/export table+graph in highcharts in PDF f

One way to do this is use drawing API and then draw table line by line while exporting PDF. Is there any other way like render html (table ) code into PDF or create table row and column wise, so that it would be easier to format or update table.

Unfortunately, it is the only solution with pure Highcharts library:

Highcharts docs: https://www.highcharts.com/docs/getting-started/frequently-asked-questions/#add-data-table.

However, more complex pdfs with multiple charts and additional elements like tables, images, titles, etc can be made following this approach:

send AJAX to Highcharts server with options for each of the charts. The return will be an URL to the image on the server.
convert images from Highcharts server into base64 format. (You can use these approaches: https://stackoverflow.com/a/20285053/10077925)
Add charts images, tables, titles, etc to pdf using the jspdf library and save the result.

Code:

$(function() {

  const toDataURL = url => fetch(url)
    .then(response => response.blob())
    .then(blob => new Promise((resolve, reject) => {
      const reader = new FileReader()
      reader.onloadend = () => resolve(reader.result)
      reader.onerror = reject
      reader.readAsDataURL(blob)
    }))

  var chartOptions = {

    title: {
      text: 'Solar Employment Growth by Sector, 2010-2016'
    },

    subtitle: {
      text: 'Source: thesolarfoundation.com'
    },
    
    exporting: {
    	showTable: true
    },
