Bootstrap last column is out of line. How to treat?

Question

Bootstrap

I am aware of the need for a negative margin-left for raw to compensate for the indent of the first column. The question is rather why it is not there and how to correctly and "adaptively" set it?

Answer 1

Where is not? What is missing?

Answer 2

Take the third bootstrap and do it on it. Your incomprehensible problems will disappear. Sense to work on the second, to be honest, I do not see.
