How thick does an oak table top with 3x3 inch table legs and a table top of 106x35 inch minimal should be for it not to bend?

Dear WoodTalk community,

 

I want to build this: https://tinkercad.com/things/hAtInhT5ox6 (very slow site). An Oak table, with a table top dimensions 270x90x4 cm (106x35x1.57 Inch) and table legs 8x8 cm (3x3inch).

 

I am worried that this design wil bend/ hog/ sag due to it's length/ width/ thickness ratio. Does anyone have a general rule of thumb to determine the minimal thickness needed for a 270x90 cm (106x35 Inch) table top for it not to bend/ hog/ sag?

 

Thanks
