行和分页的反应表组合无法按预期运行

Question

我使用react-table在表中包括行和分页，如本例所示：https://react-table.tanstack.com/docs/examples/row-selection-and-pagination.正如教程所说，我已经完成了我的示例，但它并没有按预期运行。在它停止更新selectedRowsId之前，我只能选择一行。取消选择该行也不会清除它。我做错了什么？

import React, { useMemo, forwardRef, useRef, useEffect } from "react";
import {
useTable,
useSortBy,
useFilters,
useGlobalFilter,
usePagination,
useRowSelect
} from "react-table";
import matchSorter from "match-sorter";
import '../../static/scss/table.scss'

function DefaultColumnFilter({
column: { filterValue, preFilteredRows, setFilter },
}) {
const count = preFilteredRows.length;
return (
<input
value={filterValue || ""}
onChange={(e) => {
setFilter(e.target.value || undefined); // Set undefined to remove the filter entirely
}}
placeholder={`Search ${count} records...`}
/>
);
}
function SelectColumnFilter({
column: { filterValue, setFilter, preFilteredRows, id },
}) {
// Calculate the options for filtering
// using the preFilteredRows
const options = React.useMemo(() => {
const options = new Set();
preFilteredRows.forEach((row) => {
options.add(row.values[id]);
});
return [...options.values()];
}, [id, preFilteredRows]);
// Render a multi-select box
return (
<select
value={filterValue}
onChange={(e) => {
setFilter(e.target.value || undefined);
}}
>
<option value="">All</option>
{options.map((option, i) => (
<option key={i} value={option}>
{option}
</option>
))}
</select>
);

fuzzyTextFilterFn.autoRemove = (val) => !val;

useEffect(() => {
resolvedRef.current.indeterminate = indeterminate

return (

我找到了解决方案。index.js文件的<React.StrictMode>封装了<App />。卸下<React.StrictMode>可以修复它并正常工作。这可能是一个错误，应该修复。
