[Plugin: TablePress] Maximal database size & Remove button "Delete table"

Hey, I’m using TablePress for a rather big database. There will be around 1000 rows with 9 columns data in one specific table very soon and each month I will be adding around 50 rows.
Is anyone here who is experienced with having such huge tables? Is there a limit of rows? Will filtering/searching get slow anytime soon, the more data I add? Or is this no concern at all?

Plus, I only use that one table for my entire project and there is exactly one button in the backend that I really, really fear: “Delete table” (in my German version it is “Andere Aktionen: Tabelle löschen”).
Is there any chance to remove that button entirely from the backend, so that I will never ever delete that table accidently?
