element ui的table动态生成表头，动态新增一行，并且

<el-table
                      :data="inputValueDate"
                      border
                      stripe
                      style="width: 100%;"
                    >
                      <el-table-column
                        v-for="(item1,index1) in item.optionsList"
                        :key="index1"
                        :label="item1.optionValue"
                        :property="item1.optionName"
                      >
                        <template slot-scope="scope">
                          <el-input
                            v-model="scope.row[scope.column.property]"
                            size="small"
                            style="width:100%"
                          ></el-input>
                        </template>
                      </el-table-column>
                      <el-table-column label="操作" min-width="30%">
                        <template slot-scope="scope">
                          <span @click="deleteData1(scope.row,scope.$index)">
                            <a href="javascript:;">删除</a>
                          </span>
                        </template>
                      </el-table-column>
                    </el-table>

表头的数据是这样的--包括label和props

最重要的代码是这部分

<el-table-column
                        v-for="(item1,index1) in item.optionsList"
                        :key="index1"
                        :label="item1.optionValue"
                        :property="item1.optionName"
                      >
                        <template slot-scope="scope">
                          <el-input
                            v-model="scope.row[scope.column.property]"
                            size="small"
                            style="width:100%"
                          ></el-input>
                        </template>
                      </el-table-column>
