重点是.head-box .body-box-right .body-box-left 三个类的设置

.box {
            display: flex;
            justify-content: flex-start;
        }

        table {
            width: 500px;
        }

        tr,
        th {
            display: flex;
            justify-content: space-around;
            align-content: space-around;
            height: 50px;
        }

        td {
            width: 80px;
            text-align: center;
            line-height: 50px;
        }

        .head-box {
            color: aliceblue;
            background-color: blueviolet;

            height: 300px;
            overflow-y: auto;
            /* -webkit-overflow-scrolling: touch; */
