@Vilx-Sorry, maybe I just misinterpreted the question. I agree with you there - if it is semantically a table, it should stay a table. I see no reason to be screwing with CSS in that case. You are referring to bootstrap - which part of it is it?

@Vilx-You don't need to have that on every cell. Of course if you set that on every single cell, then your point is valid.

There is also one important thing that hasn't been mentioned in the answer of JacquesB - animation. Animating the table cells is practically impossible / or is very difficult. While this is not a common thing to do, sometimes it does occur, there is another reason.
