code: function createContainer ( tableNode ) {
  
          var container = document.createElement( "div" );
          container.className = "edui-chart-container";
  
          tableNode.parentNode.replaceChild( container, tableNode );
  
          return container;
  
      }

  新创建的容器会替换掉对应的table对象
