八大排序（尚未完善）

1.效果

2.关键代码讲解

是el-form嵌套的el-table，el-form只能为对象，el-table只能为数组，所以需要对象嵌套数组的形式

自定义规则使用插槽的方式添加，要保证每个都不一样所以这个prop也得是动态的

   <el-table-column prop="name" label="姓名" width="200px">
                    <template slot-scope="scope">
                        <el-form-item
                            :prop="'tableData.' + scope.$index + '.name'"
                            :rules="{
                                required: true,
                                message: '姓名不能为空',
                                trigger: 'blur'
                            }"
                        >
                            <el-input size="small" v-model="scope.row.name" placeholder="请输入姓名" clearable></el-input>
                        </el-form-item>
                    </template>
                </el-table-column>

删除只需要删除所点击的行数据就行

     <el-button type="text" size="small" @click="tableForm.tableData.splice($index, 1)">删除</el-button>
