如何缩短material ui中Textfield中的边框与文本的距离

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import TextField from '@material-ui/core/TextField';

const useStyles = makeStyles((theme) => ({
  textField: {
    '& .MuiInputBase-root': {
      paddingTop: 6, // 调整文本上方的边距
      paddingBottom: 6, // 调整文本下方的边距
    },
    '& .MuiInputLabel-root': {
      transform: 'translate(0, 1.5px) scale(0.75)', // 调整标签的位置和大小
    },
  },
}));

const MyComponent = () => {
  const classes = useStyles();

  return (
    <TextField
      label="Label"
      variant="outlined"
      className={classes.textField}
    />
  );
};
