Spreadsheets inserted into presentations are too low resolution to be used seriously

So I tried to insert a spreadsheet into my presentation today, but I found the image to be too low resolution or otherwise unsightly to be used in practice, especially on a larger screen.
I demonstrated it here: Murena

So basically I would like the inserted spreadsheet to actually look good and presentable, whatever that takes.

Hello @DonnerWolfBach

First of all, please note that this version is outdated and not supported anymore. I’d recommend updating it to actual version for better experience.

In general, you can simply increase cells font size to scale the resulting image up with slide instead of resizing the image itself after adding it to the presentation. That way, added table image will have better resolution and you won’t need to resize it if found proper font size ratio.
