您应该仅为父 TableRow 元素设置 key 属性
您可以将 values 状态初始化为 { id, value } 形式的对象，并更新与已更改的 id 对应的值。此配置应防止由于 table 过滤和索引不匹配而导致的潜在错误：

const [values, setValues] = useState(tableData.map(data => ({ id: data.id, value: ''})));

const handleValueChange = (e, id) => {
    const otherValues = values.filter(v => v.id !== id);
    const updatedValue = { id, value: e.target.value };
    setValues({ ...otherValues, updatedValue })
}

return (
  <TableContainer>
    <Table style={{ height: 'max-content' }} stickyHeader>
        ...
      <TableBody>
        {tableData.map((data, index) => (
            <TableRow key={data.id}>
              <TableCell
                style={{
                  border: '0px solid transparent',
                  fontFamily: "'Inter', sans-serif",
                }}
                align='center'
              >
                {data.roll}
              </TableCell>
              <TableCell
                style={{
                  border: '0px solid transparent',
                  fontFamily: "'Inter', sans-serif",
                }}
                align='center'
              >
                {data.name}
              </TableCell>
              <TableCell
                style={{
                  border: '0px solid transparent',
                  fontFamily: "'Inter', sans-serif",
                }}
                align='center'
              >
                {data.email}
              </TableCell>
              <TableCell

                  border: '0px solid transparent',
                  fontFamily: "'Inter', sans-serif",
                }}
                align='center'
              >
                <input
                  type='text'
                  style={{
                    border: '1px solid black',
                    width: '66px',
                    height: '32px',

                  }}
                  required
                  value={values.find(v => v.id === data.id)?.value || ''}
                  onChange={(e) => { handleValueChange(e, data.id); }}
                />
