   DataTables enveloppe le tableau sur place : son wrapper — et donc les .row
   Bootstrap qui portent la recherche, le compteur et la pagination — se
   retrouve À L'INTÉRIEUR du .table-responsive. Or une .row porte des marges
   négatives de 0.75rem de chaque côté, qui la rendent plus large que son
   parent. Dans un conteneur en overflow-x: auto, ces 24px se traduisent
   directement en défilement latéral, alors même que le tableau tient dans la
   largeur. On neutralise donc les marges négatives ; les colonnes gardent leur
   gouttière, le contenu est simplement aligné sur le bord du conteneur. */
