给el-form加个类名class="myForm",然后添加样式

.myForm::v-deep {
    .el-row {
        .el-form-item {
            display: flex;
    
            .el-form-item__label {
                width: unset;
            }
    
            .el-form-item__content {
                margin-left: unset;
                flex: 1;
            }
        }
    }
}
