We want to keep track of how many users are choosing the Electron- and the OCG-rendering option in the ElectronPdfService extension.
One of the wishes of the 2015 German-speaking community wishlist as well as the international community wishlist was the support of tables in pdfs: T135643.
It would take an enormous engineering effort to add tables to the current latex layout in a way that 80%-90% of the tables display correctly. 10%-20% would always be off due to the different capabilities of the two media (printed, layouted page versus HTML). Therefore the idea is to offer another way of rendering pdfs. The new browser-based rendering version will not have the well designed latex layout (at least for the start), but look like the printed website - not perfect for print, but at least complete.
