In this tutorial, I will guide you on how to convert HTML tables to PDF document using jspdf library and its addhtml() method in JavaScript. Basically, the jsPDF addHTML() function accepts HTML5 code using its first parameter. It then converts the HTML5 code to PDF and gives us the option to download the PDF file using the callback function as the second parameter.
The complete source code of this project is available in this article. So, you can easily download and run it on your computer.
