搜索框过滤不返回搜索结果- React+ react-table+过滤器

import React, { useState } from 'react';
import { useTable, useFilters } from 'react-table';

const Table = ({ columns, data }) => {
  const [filterInput, setFilterInput] = useState('');

  // 定义过滤器组件
  const DefaultColumnFilter = ({ column: { filterValue, setFilter } }) => {
    return (
      <input
        value={filterValue || ''}
        onChange={(e) => {
          setFilter(e.target.value || undefined); // 设置过滤器的值
        }}
        placeholder="搜索..."
      />
    );
  };

  // 使用react-table创建表格实例
  const {
    getTableProps,
    getTableBodyProps,
    headerGroups,
    rows,
    prepareRow,
    setFilter,
  } = useTable(
    {
      columns,
      data,
    },
    useFilters // 使用过滤器
  );

  // 更新过滤器的值
  const handleFilterChange = (e) => {
    const value = e.target.value || undefined;
    setFilter('columnName', value); // columnName是你要过滤的列名
    setFilterInput(value);
  };

  return (
    <div>
      <input

                </th>
              ))}

// 使用示例
const App = () => {
  const columns = [

      Header: '姓名',
      accessor: 'name',
      Filter: DefaultColumnFilter, // 使用默认过滤器
    },

    { name: '李四', age: 30 },
    // 其他数据...

  return <Table columns={columns} data={data} />;

export default App;
