React：如何包装输入文本？

Question

我有一个使用 material-ui 编写的 React 表，如下所示：

import React from "react";
import PropTypes from "prop-types";
import { withStyles } from "@material-ui/core/styles";
import Table from "@material-ui/core/Table";
import TableBody from "@material-ui/core/TableBody";
import TableCell from "@material-ui/core/TableCell";
import TableHead from "@material-ui/core/TableHead";
import TableRow from "@material-ui/core/TableRow";
import Paper from "@material-ui/core/Paper";

const styles = theme => ({
  root: {
    width: "100%",
    marginTop: theme.spacing.unit * 3,
    overflowX: "auto"
  },
  table: {
    minWidth: 700
  }
});

let id = 0;
function createData(name, calories, fat, carbs, protein) {
  id += 1;
  return { id, name, calories, fat, carbs, protein };
}

const rows = [
  createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
  createData("Ice cream sandwich", 237, 9.0, 37, 4.3),
  createData("Eclair", 262, 16.0, 24, 6.0),
  createData("Cupcake", 305, 3.7, 67, 4.3),
  createData("Gingerbread", 356, 16.0, 49, 3.9)
];

function SimpleTable(props) {
  const { classes } = props;

  return (
    <Paper className={classes.root}>
      <Table className={classes.table}>
        <TableHead>
          <TableRow>
            <TableCell>Dessert (100g serving)</TableCell>
            <TableCell align="right">Calories</TableCell>
            <TableCell align="right">Fat (g)</TableCell>
            <TableCell align="right">Carbs (g)</TableCell>
            <TableCell align="right">Protein (g)</TableCell>
          </TableRow>
        </TableHead>
        <TableBody>
          {rows.map(row => (
            <TableRow key={row.id}>
              <TableCell component="th" scope="row">
                {row.name}
              </TableCell>
              <TableCell align="right">
                <input defaultValue={row.calories}/>
              </TableCell>
              <TableCell align="right">{row.fat}</TableCell>
              <TableCell align="right">{row.carbs}</TableCell>
              <TableCell align="right">{row.protein}</TableCell>
            </TableRow>
          ))}
        </TableBody>
      </Table>
    </Paper>
  );
}

SimpleTable.propTypes = {
  classes: PropTypes.object.isRequired
};

export default withStyles(styles)(SimpleTable);

我表格的一些单元格有<input />s（这里只是calories，因为它是一个例子）。如果输入中的文本比输入长，如何让输入中的文本换行？目前，它将其他文本推开并隐藏。

您可以使用 css 属性 overflowWrap: "break-word"。阅读更多关于它的信息https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap
