Hi,
for buttons we add class button_width on each Button element.
After that we added this code to your style.css file:
.tcvpb-button_blue.button_width {
width: 100%;
}
For table:
we answered on this question here:

our Table element is not so extensive so please try to install this plugin,it’s free:
