1、先有一下成绩单数据
scores = [
{ name: 'Bob', math: 97, chinese: 89, english: 67 },
{ name: 'Tom', math: 67, chinese: 52, english: 98 },
{ name: 'Jerry', math: 72, chinese: 87, english: 89 },
{ name: 'Ben', math: 92, chinese: 87, english: 59 },
{ name: 'Chan', math: 47, chinese: 85, english: 92 },
]
用table表格标签渲染以上数据，表格第一列是学生总分排名，最后一列是学生总分；
2、还是采用上方相同的数据，采用相同的渲染规则，只渲染所有科目都及格了的学生。
