实现表头固定，tbody 垂直滚动
准备工作：
- 获取页面可是区域高度
function setIframeHeight() {var screenHeight = document.documentElement.clientHeight;}2. 屏幕旋转触发事件
window.addEventListener("resize",()=>{
// 正常方向或者屏幕旋转 180°
if(window.orientation===180||window.orientation===0){console.log('竖屏');
}
// 屏幕顺时针旋转 90°或者逆时针旋转 90°
if (window.orientation===90||window.orientation===-90) {console.log('横屏');
}
})方法一：两个 table
思路：第一个 table 放表头，第二个 table 方内容。循环获取 tbody 第一行单元格的宽度，给 thead 的单元格，使表头对齐
