Hello Team ,I am going through Rapid Mendix Developer Course, I am trying to add 4 columns in tablet view but I could not drag the corners to make columns in square format

I assume you have a Layout grid with 4 columns and you want, when the application is running, to have it resemble a square? What do you want the application to do when the windows resize, or if it is opened on a tablet with different screen size?

It can be done, but I don't know to what extent it will break the Mendix way of working. for inspiration on how to do it using CSS and JavaScript. Bear in mind that what you see in the Mendix Studio Pro Structure Mode is not reflecting the final look and feel. For this the designer Mode is better, but not perfect.
