【问题描述】：
我想咨询一下 React UI Material 中的表格分页。
我在这里尝试实现 API 中的所有数据。
我已经成功实现的一些数据是从 API 到 Material UI Table。
- 根据请求每页的行数显示数据
- 数据来自我拥有的 API。
但是，当我尝试实现分页时，API 中的数据显示不正确。
示例： 第一次渲染组件时，它会显示来自 API 的 5 条数据。但是当我尝试移动到下一页时，只有API的响应成功，而出现的数据却没有。
这里我把它分成几个文件：
- 索引组件
- 索引容器
文件索引组件。

mapActions(

'changeRowPerPage',
'changePagination',
'createPaymentCategory',
'readPaymentCategory',
'updatePaymentCategory',
'deletePaymentCategory'
)
)(PaymentCategoryContainer)
来自 API 的响应数据：
items: [] => array. totalItems: 0 => int
有没有我遗漏的错误？还是我错过了一个步骤？。
我正在关注this部分ui材料中的示例。
谢谢。
