操作按钮隐藏

找到如下节点，在 optShow 中设置表格上方的按钮显与隐

cruds() {
    return [
      CRUD({ title: '字典详情', url: 'api/dictDetail', query: { dictName: '' }, sort: ['dictSort,asc', 'id,desc'],
        crudMethod: { ...crudDictDetail },
        optShow: {
          add: true,
          edit: true,
          del: true,
          reset: false
        },
        queryOnPresenterCreated: false
      })
    ]
  }
