如何在ng2-smart-table上使用* ngxPermissionOnly隐藏/显示自定义操作图标

Question

下面是我的代码，但这不起作用 动作：{         编辑：false，         添加：false，         删除：false，

    custom: [
      {
        type: 'html',
        name: "Details",
        title: `<i id="view" class="fa fa-eye pointer color-blue" title="View Entity" *ngxPermissionsOnly='[permissions.ENTITY_VIEW_DETAILS]'></i> &nbsp; `,
       mode:external
      },
      {mode: 'external',
        type: 'html',
        name: 'Assign Plans',
        title: `<i id='plans' class="fa fa-tasks pointer" data-toggle="tooltip" title="Assign plans" *ngxPermissionsOnly='[permissions.ENTITY_VIEW_ASSIGNPLANS]'></i> &nbsp; `,

      },
      {
        type: 'html',
        name: 'edit',
       title: `<i id="edit" class="fa fa-pencil pointer color-orange" data-toggle="tooltip" title="Update Entity" *ngxPermissionsOnly='[permissions.ENTITY_VIEW_EDIT]'></i>  &nbsp;`
      },
      {
        type: 'html',
        name: 'delete',
        title: `<i id="delete" class="fa fa-trash pointer color-danger" data-toggle="tooltip" title="Delete Entity"  *ngxPermissionsOnly='[permissions.ENTITY_VIEW_DELETEENTITY]'></i>`,
      },

    ],`

请帮助我，谢谢！
