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-column
        prop="name"
        label="编号"
        width="180">
      </el-table-column>
      <el-table-column
        prop="address"
        label="排序">
         <template slot-scope="scope">
			<el-button
                  type="text"
                  disabled={index === 0}
                  @click={e => this.sortFunction(e, row, "1")}
                >
                  上移
                </el-button>
                <el-button
                  type="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
