angular - Ng2智能表，从一个对象中获取多列

Question

我正在使用 ng2 智能列来显示包含用户对象的交易。我想在不同的列中显示 id 用户、姓名和电子邮件。我该怎么做？

settings = {
    add: {
      addButtonContent: '<i class="nb-plus"></i>',
      createButtonContent: '<i class="nb-checkmark"></i>',
      cancelButtonContent: '<i class="nb-close"></i>',
      confirmCreate : true
    },
    edit: {
      editButtonContent: '<i class="nb-edit"></i>',
      saveButtonContent: '<i class="nb-checkmark"></i>',
      cancelButtonContent: '<i class="nb-close"></i>',
      confirmSave : true
    },
    delete: {
      deleteButtonContent: '<i class="nb-trash"></i>',
      confirmDelete: true,
    },
    columns: {
      id: {
        title: 'ID',
        type: 'number',
      },
   
      user: { 
        title : 'name',
      valuePrepareFunction: (data) => {
                                   return data.email;
                               },
       },

      amount: {
        title: 'Valeur',
        type: 'number',
       
      },
      items: {
        name: { title: 'Nom' },
    },

      state: {
        title: 'Etat',
        type: 'string',
      },
      delivery_date: {
        title: 'Date de livraison',
        type: 'string',
      },
      expedition_date: {
        title: 'Date d\'expedition',
        type: 'string',
      },
    },
  };
