需求：table排序，可操作排序上移下移功能。判断第一行上移禁用和最后一行下移禁用，排序根据后端返回的字段

 <el-table:data="tableData"style="width: 100%"><el-table-column type="index" label="序号" align="center" min-width="50"><template slot-scope="scope"><span>{{ scope.$index + (pageNum - 1) * pageSize + 1 }}</span></template></el-table-column><el-table-columnprop="name"label="编号"width="180"></el-table-column><el-table-columnprop="address"label="排序"><template slot-scope="scope"><el-buttontype="text"disabled={index === 0}@click={e => this.sortFunction(e, row, "1")}>上移</el-button><el-buttontype="text"disabled={index === this.tableData.length - 1}@click={e => this.sortFunction(e, row, "2")}>下移</el-button></el-table-column></el-table-column><el-table-column prop="address" label="操作" min-width="200" align="center"><template slot-scope="scope"><el-button>编辑</el-button><el-button  @click="handleDelete(scope.row)">删除</el-button></template></el-table-column></el-table>

sortFunction(e, row, type) {changeSort({//排序接口sortType: type,templateConfigId: row.templateConfigId}).then(res => {if (res.code === 200) {this.getList();//获取表格接口}});},

按钮上一条下一条功能

            <div class="right-bottom"><el-buttonclass="end-upon btns":disabled="uponindex === 0":class="isEndBtn === true ? 'isActive' : ''"@click="endUponClick()">上一条</el-button><el-buttonclass="end-next btns":disabled="isDisabled":class="isNextBtn === true ? 'isActive' : ''"@click="endNextClick()">下一条</el-button></div>
