                                          Table 隐藏列自动保存

页面中配置crudOperation :tableKey='tableKey'

```
<!--如果想在工具栏加入更多按钮，可以使用插槽方式， slot = 'left' or 'right'-->
      <crudOperation :permission="permission" :tableKey='tableKey' />
```

在data 中添加 tabkeKey

```
data() {
    return {
      queryTypeOptions: [
        { key: 'code', display_name: '代码' },
        { key: 'name', display_name: '名称' },
        { key: 'enabled', display_name: '状态' },
        { key: 'heat', display_name: '热度' }
      ],
      permission: {
        add: ['admin', 'area:add'],
        edit: ['admin', 'area:edit'],
        del: ['admin', 'area:del']
      },
      tableKey:'api/area',
      rules: {
        code: [
          { required: true, message: '库区编号不能为空', trigger: 'blur' }
        ]
      }
    }
  }
```

全部代码

```
