如何隐藏材质ui表格单元格中的溢出内容而不是换行

Question

我正在使用材质 UI 表格组件来呈现表格。当单元格中的内容溢出时，我想显示... 省略号。当前的行为是它将文本包装在单元格内。我尝试添加 CSS 样式但无济于事。我如何做到这一点？

import React from "react";
// import { makeStyles } 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 TableContainer from "@material-ui/core/TableContainer";
import TableHead from "@material-ui/core/TableHead";
import TableRow from "@material-ui/core/TableRow";
import Paper from "@material-ui/core/Paper";

function createData(name, calories, fat, carbs, protein) {
  return { name, calories, fat, carbs, protein };
}

const rows = [
  createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
  createData(
    "Ice cream sandwich dsdadsads dsadsadsadsa dsadasdsadsa dsadsadsa dsadsads asdsadsadsadsa",
    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)
];

export default function SimpleTable() {
  return (
    <TableContainer component={Paper}>
      <Table aria-label="simple table">
        <TableHead>
          <TableRow>
            <TableCell>Dessert (100g serving)</TableCell>
            <TableCell align="right">Calories</TableCell>
          </TableRow>
        </TableHead>
        <TableBody>
          {rows.map(row => (
            <TableRow key={row.name}>
              <TableCell style={{root:{overflowX: 'hidden', textOverflow: "ellipsis"}}} className="overflow-test" component="th" scope="row">
                {row.name}
              </TableCell>
              <TableCell align="right">{row.calories}</TableCell>
            </TableRow>
          ))}
        </TableBody>
      </Table>
    </TableContainer>
  );
}

.overflow-test {
  overflow-x: hidden !important;
  text-overflow: ellipsis !important;
}

给你一个解决方案

import React from "react";
// import { makeStyles } 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 TableContainer from "@material-ui/core/TableContainer";
import TableHead from "@material-ui/core/TableHead";
import TableRow from "@material-ui/core/TableRow";
import Paper from "@material-ui/core/Paper";

import Css from "./styles.css";

function createData(name, calories, fat, carbs, protein) {
  return { name, calories, fat, carbs, protein };
}

const rows = [
  createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
  createData(
    "Ice cream sandwich dsdadsads dsadsadsadsa dsadasdsadsa dsadsadsa dsadsads asdsadsadsadsa",
    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)
];

export default function SimpleTable() {
  return (
    <TableContainer component={Paper}>
      <Table aria-label="simple table">
        <TableHead>
          <TableRow>
            <TableCell>Dessert (100g serving)</TableCell>
            <TableCell align="right">Calories</TableCell>
          </TableRow>
        </TableHead>
        <TableBody>
          {rows.map(row => (
            <TableRow key={row.name}>
              <TableCell component="th" scope="row">
                <div className={Css.textContainer}>
                 {row.name}
                </div>
              </TableCell>
              <TableCell align="right">{row.calories}</TableCell>
            </TableRow>
          ))}
        </TableBody>
      </Table>
    </TableContainer>
  );
}

.textContainer {
  display: block;
  width: 200px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

您需要为容器指定宽度，然后对其应用省略号样式。

两个注意点

• inline-styles 中不需要 root，删除它

• ... 的 CSS

  style={{
    whiteSpace: "nowrap",
    textOverflow: "ellipsis",
    width: "300px",
    display: "block",
    overflow: "hidden"
  }}

要使溢出的单元格保持响应，请将table-layout: fixed; 添加到表格组件。如果需要 TableCell 可以指定width: auto 或固定宽度。
