Faire un kanban

Bonjour, j'ai télécharger un template avec un kanban pour m'entrainer en php ajax etc mais malgrès tout les tutos et forums je n'arrive pas a trouver une technique pour enregistre le kanban dans une base de donnée.

pour le début j'ai réaliser une base donnée :


je suis partis du faite qui il a une colonne vide comme ca :

Voila un rendu visuel du template a vide :



Dans la note du template le créateur utilise Jkanban une biblio pour crée des kanbans facilement (sans les explications de comment le mettre en relation avec une base de donnée)

voici le code js :

$(document).ready(function (){
  var kanban_curr_el, kanban_curr_item_id, kanban_item_title, kanban_data, kanban_item, kanban_users;

  // Kanban Board and Item Data passed by json
  var kanban_board_data = [{
      id: "kanban-board-1",
      title: "Marketing",
      item: [{
          id: "11",
          title: "Facebook Campaign ????",
          border: "success",
