When it comes to 'removing' banner and footer:
The easiest way is to do this with css
for example
body.section-produtos #portal-header{
display: none;
}
Your problem is that the markup is a bit insane, so it does not look like you have an ID to 'hide'.
My opinion:
As gyst said: drop everything 'with tables' (is this a Plone 4 site ?)
Do the items with flex box (unless most of your users have old browsers)
With this approach, it can be used on mobile easily.
I've already know how to remove what I need, $(".visualNoPrint").empty() do the job, I'm trying to do it when a frame open this site bue my javascript it isn't executed on plone site
