Post with a table which is not responsive

Hello,

I contact you because I have a site with the Enfold (Child) theme, and for the moment I have two posts on it.
The first one is well responsive, there is no worry when I look at it via my mobile phone.
But, the second post, in which there is a table, does not work correctly. When I look at my post via my computer, the post is like I wish. But, when I look at the post via a mobile phone, it’s not right at all. The table does not appear as it should, there are duplicates, titles (in the table) are not displayed at the correct place and everything is mixed up..
(And if, in the table’s options, I choose “Make the table scrollable” (and not “Set the table at the size of the screen” -or something like that, because I have the French version-), the visual is a little bit better (my table keeps its appearance), but the sentences overlap and go over the sentences of the next column..)

How come ? And what can I do to fix this ?

Too see exactly what I am talking about, here is my post : http://www.unvoyagepourdeux.com/carnet-de-voyage/nos-sacs-a-dos/

And I join two images :
The first one, the view of my post on a mobile phone, with the styling responsive “Set the table at the size of the screen” :

The second one, the view of my post on a mobile phone, with the styling responsive “Make the table scrollable” (I prefer this one because the appaerance of my table looks better, but the sentences are a problem..) :

Thank you !

Regards,

Maëva
