♻️(front) improve table pdf rendering

The previous way of rendering table was causing issues when tables
could not fit on one page. I then came accross this discussion
https://github.com/diegomura/react-pdf/issues/2343. The author
created a lib to improve the rendering of table, it's better, but
still not perfect maybe.
