In order to render tweetable PNGs of my WRC rally stage chartables, I’ve been using selenium to render the table in its own web page and then grab a screenshot (Converting Pandas Generated HTML Data Tables to PNG Images), but that’s really clunky. So I started to wonder: are there any HTML2PNG converters out there?
This post has some handy pointers, including reference to the following packages:
- HTML2Canvas, which allows you to take “[s]creenshots with JavaScript” and export them as PNG files;
- TableExport, which seems to work with jspdf (“the leading HTML5 client solution for generating PDFs”) and jsPDF-AutoTable (a “jsPDF plugin for generating PDF tables with javascript”) to allow you to export an HTML table as a PDF.
The html2canvas route is also demonstrated in this Stack Overflow answer offered in answer to a query wondering how to Download table as PNG using JQuery.
So now I’m wondering a couple of things about styled pandas tables in Jupyter notebooks.
Firstly, would some magic __repr__ extensibilty that provides a button for exporting a styled pandas table as a PNG or a PDF be handy?
Secondly, how could the above recipes be woven into a simple end user developed ipywidgets powered app (such as the one I used to explore WRC stage charts) to provide a button to download a rendered, styled HTML table as a PNG or PDF?
Anyone know of such magic / extensions already out there? Or can knock up a demo, ideally a Binderised one, showing me how to do it?
