data定义的数据，处理数据按照这个格式处理即可：

   tableData1: [
                {
                    name: "B1",
                    temperatures: [
                        { type: "最高温", value: 30 },
                        { type: "最低温", value: 10 },
                        { type: "平均温", value: 20 },
                    ],
                },
                {
                    name: "B2",
                    temperatures: [
                        { type: "最高温", value: 35 },
                        { type: "最低温", value: 15 },
                        { type: "平均温", value: 25 },
                    ],
                },
            ],

调用边框的方法:

 methods: {
        getCellClass() {
            return "table-cell-border";
        },

<style scoped>
::v-deep .table-cell-border {
    border: 1px solid #b3b3b3; /* 调整边框的颜色和样式 */
}
::v-deep .no-header .el-table__header-wrapper {
    display: none;
}
</style>

成果：
