el-table设置单元格行高间距

（1）定位修改元素

（2）通过deep进行样式修改

<style  lang="scss" scoped>

/*  lang="scss" 用了 scss 使用::v-depp{} 穿透修改样式
   未使用scss   直接用/deep/ {修改样式}
*/  
::v-deep {

    /**el-table表格调整 start*/
    .el-table .el-table__header-wrapper th,
    .el-table .el-table__fixed-header-wrapper th {
        height: auto;
        padding: 2px 0;
    }

    .el-table--mini .el-table__cell {
        padding: 2px;
        flex: 1;
    }

    /**el-table表格调整 end */
}
</style>

// 不使用sass
<style  scoped>
/deep/ .el-table .el-table__header-wrapper th,.el-table .el-table__fixed-header-wrapper th {
        height: auto;
        padding: 2px 0;
