【React】Ant Design 5.x 实现tabs圆角及反圆角效果

需要实现的效果

实现思路

利用tab页的before和after属性，添加tab页前后的圆弧属性，同时使用tab页的shadow阴影填充右下角的圆弧空缺部分。

            <Tabs
                onChange={onChange}
                type="card"
                items={getTabItems()}
            />

.ant-tabs-nav{
        margin: 0;

        .ant-tabs-nav-list{
            display: flex;
            position: relative;
            z-index: 2;
            width: 100%;
            background: #E1E8F2;
            border-radius: 24px 24px 0 0;
            overflow: hidden; // 重点
            user-select: none;
        }

        .ant-tabs-tab{
            flex: 1;
            position: relative;
            display: flex;
