HTML、CSS表格的斜表头样式设置title 画对角线

我里面有用到layui框架的影响，实际根据你自己的框架来小调下就可以

效果如下

上代码

<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>对角线单元格示例</title>
    <style>
      

        /* 模拟对角线 */
        .oline {
            border-top: 40px #fff solid;
            /*上边框宽度等于表格第一行行高*/
            width: 0px;
            /*让容器宽度为0*/
            height: 0px;
            /*让容器高度为0*/
            border-left: 80px #fff solid;
            /*左边框宽度等于表格第一行第一格宽度*/
            position: relative;
            /*让里面的两个子容器绝对定位*/

        }

        .oline::before {
            position: absolute;
            top: -49px;
            left: -95px;
