为 Material UI TablePagination 中的每个菜单项添加唯一 ID

Question

是否可以为使用 <TablePagination > 呈现的每个菜单项添加唯一 ID？

我想给这（10、25、100）个菜单项添加一个唯一ID（例如：id="menu_item_0"、id="menu_item_1" & id="menu_item_2"），基本上是<li> 标签。

这是代码。

import * as React from "react";
import Paper from "@mui/material/Paper";
import Table from "@mui/material/Table";
import TableBody from "@mui/material/TableBody";
import TableCell from "@mui/material/TableCell";
import TableContainer from "@mui/material/TableContainer";
import TableHead from "@mui/material/TableHead";
import TablePagination from "@mui/material/TablePagination";
import TableRow from "@mui/material/TableRow";

const columns = [
  { id: "name", label: "Name", minWidth: 170 },
  { id: "code", label: "ISO\u00a0Code", minWidth: 100 },
  {
    id: "population",
    label: "Population",
    minWidth: 170,
    align: "right",
    format: (value) => value.toLocaleString("en-US")
  }
];

function createData(name, code, population, size) {
  const density = population / size;
  return { name, code, population, size, density };
}

const rows = [createData("India", "IN", 1324171354, 3287263)];

export default function StickyHeadTable() {
  const [page, setPage] = React.useState(0);
  const [rowsPerPage, setRowsPerPage] = React.useState(10);

  const handleChangePage = (event, newPage) => {
    setPage(newPage);
  };

  const handleChangeRowsPerPage = (event) => {
    setRowsPerPage(+event.target.value);
    setPage(0);
  };

  return (
    <Paper sx={{ width: "100%", overflow: "hidden" }}>
      <TableContainer sx={{ maxHeight: 440 }}>
        <Table stickyHeader aria-label="sticky table">
          <TableHead>
            <TableRow>
              {columns.map((column) => (
                <TableCell
                  key={column.id}
                  align={column.align}
                  style={{ minWidth: column.minWidth }}
                >
                  {column.label}
                </TableCell>
              ))}
            </TableRow>
          </TableHead>
          <TableBody>
            {rows
              .slice(page * rowsPerPage, page * rowsPerPage + rowsPerPage)
              .map((row) => {
                return (
                  <TableRow hover role="checkbox" tabIndex={-1} key={row.code}>
                    {columns.map((column) => {
                      const value = row[column.id];
                      return (
                        <TableCell key={column.id} align={column.align}>
                          {column.format && typeof value === "number"
                            ? column.format(value)
                            : value}
                        </TableCell>
                      );
                    })}
                  </TableRow>
                );
              })}
          </TableBody>
        </Table>
      </TableContainer>
      <TablePagination
        rowsPerPageOptions={[10, 25, 100]}
        component="div"
        count={rows.length}
        rowsPerPage={rowsPerPage}
        page={page}
        onPageChange={handleChangePage}
        onRowsPerPageChange={handleChangeRowsPerPage}
      />
    </Paper>
  );
}

Answer 1

label 和 value 可以分别传递给 rowsPerPageOptions

rowsPerPageOptions={[
  {
    value: 10,
    label: <span id="menu_item_0">10</span>
  },
  {
    value: 25,
    label: <span id="menu_item_1">25</span>
  },
  {
    value: 100,
    label: <span id="menu_item_2">100</span>
  },
]}
