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;width: 110px;height: 58px;background: #E3ECFF url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lIHgxPSIwIiB5MT0iMCIgeDI9IjEwMCUiIHkyPSIxMDAlIiBzdHJva2U9IiNDRUQzREMiIHN0cm9rZS13aWR0aD0iMSIvPjwvc3ZnPg==) no-repeat 100% center;content: '';}.span1 {font-style: normal;display: block;position: absolute;top: -42px;left: -43px;width: 56px;}.span2 {font-style: normal;display: block;position: absolute;top: -15px;left: -93px;width: 59px;}</style>
</head>
