Antd给表格一个斜线分隔（通过css改变）

react 代码：

const [
		columns,
		setColums
	] = useState([
			//   主要代码
			title: <div style={{ 
                "position": "relative" 
            }}>
                <div style={{ "text-align": "right" }}>参数</div>
                <div style={{ "text-align": "left" }}>变量</div>
                <div style={{ 
                    "content": "", 
                    "position": "absolute", 
                    "width": "1px", 
                    "height": "140px", 
                    "top": "-48px", 
                    "left": "42px", 
                    "backgroundColor": "#1A3A50", 
                    "display": "block", 
                    "transform": "rotate(-57deg)" 
                }}>
                </div>
            </div>,
            dataIndex: "indexName",
            key: "indexName",
            width: "9%"
	])

vue antd 项目代码：
虽然框架不一样，但是实现方式是一样的。

<a-tab-pane key="2" tab="收费公示" force-render>
          <div class="shoufei">
            <p style="margin-bottom:20px">
              公示时间：{{ detailInfo.pubStartdate }}至{{detailInfo.pubEnddate}}
            </p>
            
            <!-- 表格 -->
            <div id="tableID">

}

实现方式：
写一个空div，设置长200px，高1px。再通过css旋转 transform: rotate(77deg)。然后定位上去，最好是给这个空的div加一个父盒子，利用子绝父相。
核心代码

transform: rotate(77deg);//旋转
position: absolute;//定位
// 旋转角度和定位距离根据实际情况调...
