平时写表格都直接table然后tr td就完事了，其中还是有很多不完善的，今天按照标准写了个日历，带样式。供日后写表格提供一个参考，搞前端规范还是挺重要的

css部分：

  font-size:16px;
  line-height:1.125em; /* Baseline grid of 18px */
}

/* tables may still need ‘cellspacing="0"‘ in the markup */
table.cal {
    border-collapse: seperate;
    border-spacing: 0;
    text-align: center;
    color: #333;
