我正在使用React + Material 表。
实现什么
我想选择将pageSize设置为“全部”以匹配 Material 表中的总行数。
我做了什么
我使用useState
创建rowsPerPage,并在handleChangeRowsPerPage函数中设置rowsPerPage。我使用组件重写来自定义分页,并将rowsPerPage和处理程序传递给它的 Prop 。我还将rowsPerPage传递给MaterialTable的pageSize选项。
问题我遇到
页面不会调整大小,并且state.pageSize不会更新。即使props.options.pageSize和Pagination使用onChangeRowsPerPage成功更新。

import React, { useState } from "react";
import MaterialTable from "material-table";
import { TablePagination } from "@material-ui/core";
export default function ComponentOverriding() {
const [rowsPerPage, setRowsPerPage] = useState(5);
//updates pagination, but no re-size
const handleChangeRowsPerPage = event => {
//enable to set rows per page to match total count
event.target.value === "All"
? setRowsPerPage(data.length)
: setRowsPerPage(event.target.value);
};
const data = [
{ name: "Mehmet", surname: "Baran", birthYear: 1987 },
{ name: "Zerya Betül", surname: "Baran", birthYear: 2017 }
];
return (
<MaterialTable
title="Component Override Demo"
columns={[
{ title: "Name", field: "name" },
{ title: "Surname", field: "surname" },
{ title: "Birth Year", field: "birthYear" }
]}
data={data}
//options.pageSize updates, but no re-size
options={{ pageSize: rowsPerPage }}
// onChangeRowsPerPage={handleChangeRowsPerPage} //TypeError Cannot read property 'value' of undefined
components={{
Pagination: props => (
<TablePagination
{...props}
rowsPerPageOptions={[5, 10, 20, "All"]}
rowsPerPage={rowsPerPage}
//updates pagination, but no re-size
onChangeRowsPerPage={handleChangeRowsPerPage}
/>
)
}}
/>
);
}
最佳答案
我有解决办法,
无需自定义分页
只需更换
<MaterialTable
options={{
pageSize: rowsPerPage,
pageSizeOptions: [5, 10, 20],
}}
/>
和<MaterialTable
options={{
pageSize: rowsPerPage,
pageSizeOptions: [5, 10, 20, { value: data.length, label: 'All' }],
}}
/>
