推荐答案

您可以为此使用JavaScript功能:

You can just use JavaScript features for this:

const styles = theme => {
  const cellItem = {
    color: "black",
    fontWeight: "bold",
    [theme.breakpoints.down("xs")]: {
      fontSize: "0.8em"
    }
  };
  return {
    cellItem,
    tableCellItem: {
      ...cellItem,
      fontSize: "1.5em"
    },
    tableCellItemInSingleScreen: {
      ...cellItem,
      fontSize: "2.5em"
    }
  };
};

JSS中有一个扩展插件这会导致您的语法正常工作，但它不是插件默认情况下包含在Material-UI中，但是您可以添加该插件.

There is an extend plugin within JSS that would cause your syntax to work, but it is not one of the plugins included within Material-UI by default, but you can add that plugin.
