Problem with Tablepress plugin and responsive table

Hi there:

I’m using the Tablepress plugin and the responsive table doesn’t work properly, and it seems to be due to the theme.

What happens is that the table occupies the full width of the device but the rest of the content is reduced. I don’t know why. I would like the table to be able to scroll sideways and the rest of the page to stay in the right proportion.

Any help?

Thanks in advance.
