Huh? Who would name their table? It's just furniture. Didn't live for more than like a minute either.
It needs specialized magicians using special mental barriers to read grimoires... even if they themselves were the ones to write them:
That means Grimoire mind crush, like the table's is, scales above the basic mind resistance all magicians have:
Using that K.O.'s them, but magicians are known to be mindhaxable by Grimoires in any case (there are examples of that such as Brunhild vs Kanzaki in Toaru Majutsu no Index: Kanzaki SS or during the Three Stories Arc in Volume 5).
The basic resistance of magicians covers mind control attempts by Shoukohou Misaki (See NT 22R Chapter 3 Part 2), who can do stuff like this quite casually:
In fact, she is mentioned to be able to at least control people in the triple digits:
So she is a good bit above baseline and, by scaling, the table is even more.
Also, if that dude is already getting passive mindcrushed due to that rune, wouldn't taking additional mindcrushing be just as likely to overwhelm him as if he had no feats? He would have to bear the combined mindcrushing, after all.
