如何在React material-ui中使用地图内部的网格

Question

我使用React js。我想使用Grid，但在这种情况下我不能。我有一个名为CardComponent.js的组件。问题是我使用了map函数。我不知道如何使用网格。

import React from "react";

const rows = [
  {
    id: 7,
    email: "[email protected]",
    first_name: "Michael",
    last_name: "Lawson"
  },
  {
    id: 8,
    email: "[email protected]",
    first_name: "Lindsay",
    last_name: "Ferguson"
  },
  {
    id: 9,
    email: "[email protected]",
    first_name: "Michael",
    last_name: "Lawson"
  },
  {
    id: 10,
    email: "[email protected]",
    first_name: "Lindsay",
    last_name: "Ferguson"
  }
];

const ElevatedCardHeader = () =>
  rows.map(row => (
    <Card className={"MuiElevatedCard--01"}>
      <CardHeader
        className={"MuiCardHeader-root"}
        title={row.id}
        subheader={row.email}
        classes={{
          title: "MuiCardHeader-title",
          subheader: "MuiCardHeader-subheader"
        }}
      />
      <CardContent className={"MuiCardContent-root"}>
        <Grid container spacing={2}>
          <Grid item xs={12} sm={6}>
            <Grid container>
              <Grid container justify="space-evenly">
                <label>first_name:</label>
                <label>{row.first_name}</label>
              </Grid>
            </Grid>
            <Divider light />
          </Grid>

          <Grid item xs={12} sm={6}>
            <Grid container>
              <Grid container justify="space-evenly">
                <label>last_name:</label>
                <label>{row.last_name}</label>
              </Grid>
            </Grid>
            <Divider light />
          </Grid>
        </Grid>
      </CardContent>
    </Card>
  ));
export default ElevatedCardHeader;

如何使用网格每行显示2张卡？当前，每行显示1张卡。在这里您可以看到我的Codesandbox预先感谢您的帮助和指导

            </CardContent>
          </Card>
        </Grid>
      ))
    }
    </Grid>
  )
}

您在父级上缺少grid container：

<Grid container>
  {rows.map(row => (
    ...
  ))}
</Grid>
