Question

尝试在CSS中使用与此等价的材料ui编写样式

.deleted td {
    background: red
}

但不确定如何以实际用户界面的CSS in JS方式进行操作。

以下是我目前拥有的相关摘要

const styles = theme => ({
    deleted: {
        background: '#eee'
    }
})

<TableRow className={classes.deleted}>
    <TableCell></TableCell>
</TableRow>

它应生成类似于以下内容的样式：

.deleted td {
    background: red
}

Answer 1

以防万一有人在看，这是选择具有data属性的子级的方法：

    ...
    root: {
    "& span[data-index='0']": {
        transform: 'translateX(-15%)',
    },
    "& span[data-index='3']": {
        ...
    }
   },
   ...

根据@josh的建议，使用&

  deleted: {
    "& td": {
      background: "red"
    }
  }

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

export default withStyles(styles)(SimpleTable);
