我试图在小屏幕上隐藏MUI表中的列。我严格按照文档操作,但得到的结果不稳定。想知道是否有人有解决方案或变通方法。

  return {
    name,
    calories,
    fat,
    carbs,
    protein,
    price,
    history: [
      {
        date: '2020-01-05',

    ],
  };
}

function Row(props) {
  const { row } = props;
  const [open, setOpen] = React.useState(false);

  return (

                      <TableCell align="right">
                        {Math.round(historyRow.amount * row.price * 100) / 100}
                      </TableCell>
                    </TableRow>

            </Box>
          </Collapse>
        </TableCell>
      </TableRow>
    </React.Fragment>
  );
}

Row.propTypes = {
  row: PropTypes.shape({
    calories: PropTypes.number.isRequired,
    carbs: PropTypes.number.isRequired,
    fat: PropTypes.number.isRequired,
    history: PropTypes.arrayOf(

        amount: PropTypes.number.isRequired,
        customerId: PropTypes.string.isRequired,
        date: PropTypes.string.isRequired,
      }),
    ).isRequired,
    name: PropTypes.string.isRequired,
    price: PropTypes.number.isRequired,
    protein: PropTypes.number.isRequired,
  }).isRequired,
};

const rows = [
  createData('Frozen yoghurt', 159, 6.0, 24, 4.0, 3.99),
  createData('Ice cream sandwich', 237, 9.0, 37, 4.3, 4.99),
  createData('Eclair', 262, 16.0, 24, 6.0, 3.79),
  createData('Cupcake', 305, 3.7, 67, 4.3, 2.5),
  createData('Gingerbread', 356, 16.0, 49, 3.9, 1.5),
];

export default function CollapsibleTable() {
  return (
    <TableContainer component={Paper}>
      <Table aria-label="collapsible table" >
        <TableHead>
          <TableRow>
            <TableCell />
            <TableCell>Dessert (100g serving)</TableCell>
            <TableCell align="right" sx={{ display: { xs: 'none', sm: 'block' } }}>Calories</TableCell>
            <TableCell align="right">Fat&nbsp;(g)</TableCell>
            <TableCell align="right">Carbs&nbsp;(g)</TableCell>
            <TableCell align="right">Protein&nbsp;(g)</TableCell>
          </TableRow>
        </TableHead>
        <TableBody>
          {rows.map((row) => (
            <Row key={row.name} row={row} />
          ))}
        </TableBody>
      </Table>
    </TableContainer>
  );
}

不幸的是,sx={{ display: { xs: 'none', sm: 'block' }在桌面上给了我这个结果:

它隐藏了较小屏幕上的行,但正如您所看到的,它正在分割桌面上的分隔符(并将列标题上的分隔符向上推了一点点)。

您需要替换此样式:

sx={{ display: { xs: 'none', sm: 'block' }

使用此样式:

sx={{ display: { xs: 'none', sm: 'table-cell' }

在头部和主体TableCell中,因为其默认值是table-cell
您可以查看this sandbox中的一个实时示例。

如果你想得到一个Angular答案。就是这个。输入代码:html格式(根据您的代码进行调整):

<mat-header-row *matHeaderRowDef="getDisplayedColumns()"></mat-header-row>
<mat-row *matRowDef="let row; columns: getDisplayedColumns()"></mat-row>
<mat-footer-row *matFooterRowDef="getDisplayedColumns()"></mat-footer-row>

在.ts中,使类实现OnInit和OnDestroy
声明这些方法

isPortrait() {
    return !this.landscape.matches;
  }  
  handlerOrientation: any;

https://code.daypilot.org/79036/angular-calendar-detect-orientation-change-landscape-portrait横向=窗口.匹配媒体(“(方向:风景)”);

ngOnDestroy(): void {
    console.log('on destroy');
    //https://stackoverflow.com/questions/46906763/how-to-remove-eventlisteners-in-angular-4
    //https://code.daypilot.org/79036/angular-calendar-detect-orientation-change-landscape-portrait
    this.landscape.removeEventListener("change", this.handlerOrientation, true);
  }

  private onChangeOrientation() {
    console.log('landscape orientation');
  }

  //https://code.daypilot.org/79036/angular-calendar-detect-orientation-change-landscape-portrait
  landscape = window.matchMedia("(orientation: landscape)");

   getDisplayedColumns() : string[] {
            let exibir = !this.isPortrait();
            return this.displayedColumns.filter(cd => exibir || cd.showMobile).map(cd => cd.def);}

以这种方式声明列

displayedColumns = [{ def: 'data', showMobile: true}, { def: 'numero', showMobile: false}];

}
在OnInit中输入以下内容

this.handlerOrientation = this.onChangeOrientation.bind(this);
this.landscape.addEventListener("change", this.handlerOrientation, true);
