# 旧输出参数cli-output-rows，cli-output-cols，cli-output-num如何使用？
通过KooCLI调用云服务API，默认会返回json格式的调用结果。KooCLI支持使用"--cli-output-rows"，"--cli-output-cols"，"--cli-output-num"参数，以table格式输出，方便提炼调用结果中的关键信息，如下：
以默认的json格式输出原调用结果：
```
hcloud ECS NovaListServers --cli-region="cn-north-4" --project_id="0dd8cb****************19b5a84546"
{
  "servers": [
    {
      "name": "ecs-a6b4",
      "links": [
        {
          "rel": "self",
          "href": "https://ecs.cn-north-4.myhuaweicloud.com/v2.1/0dd8cb****************19b5a84546/servers/4f06****-****-****-****-****04dd856a"
        },
        {
          "rel": "bookmark",
          "href": "https://ecs.cn-north-4.myhuaweicloud.com/0dd8cb****************19b5a84546/servers/4f06****-****-****-****-****04dd856a"
        }
      ],
      "id": "4f06****-****-****-****-****04dd856a"
    },
    {
      "name": "hdn-docker",
      "links": [
        {
          "rel": "self",
          "href": "https://ecs.cn-north-4.myhuaweicloud.com/v2.1/0dd8cb****************19b5a84546/servers/6731****-****-****-****-****0bc463f0"
        },
        {
          "rel": "bookmark",
          "href": "https://ecs.cn-north-4.myhuaweicloud.com/0dd8cb****************19b5a84546/servers/6731****-****-****-****-****0bc463f0"
        }
      ],
      "id": "6731****-****-****-****-****0bc463f0"
    },
    {
      "name": "ecs-8f88",
      "links": [
        {
          "rel": "self",
          "href": "https://ecs.cn-north-4.myhuaweicloud.com/v2.1/0dd8cb****************19b5a84546/servers/06a2****-****-****-****-****c79a1a26"
        },
        {
          "rel": "bookmark",
          "href": "https://ecs.cn-north-4.myhuaweicloud.com/0dd8cb****************19b5a84546/servers/06a2****-****-****-****-****c79a1a26"
        }
      ],
      "id": "06a2****-****-****-****-****c79a1a26"
    }
  ]
}
```
以table输出调用结果时，"--cli-output-rows"指定json结构体的层级，即表格的数据来源；"--cli-output-cols"指定表格的列名，需要与json结构体中的字段相对应；"--cli-output-num"指定是否打印表格行号，默认值为true，如下图所示:
hcloud ECS NovaListServers --cli-region="cn-north-4" --project_id="0dd8cb\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*b5a84546" --cli-output-rows="servers" --cli-output-cols="name,id"

使用"--cli-output-rows"，"--cli-output-cols"，"--cli-output-num"参数也可以用于系统命令中，如下所示：
hcloud configure list --cli-output-rows="profiles\[\]"
![](https://support.huaweicloud.com/hcli_faq/zh-cn_image_0000001606469501.png "点击放大")
hcloud configure list --cli-output-rows="profiles\[0\]" --cli-output-cols="name,accessKeyId,secretAccessKey,projectId,region"

使用"--cli-output-rows"，"--cli-output-cols"，"--cli-output-num"进行table输出时的其他注意事项[如下所示](https://support.huaweicloud.com/hcli_faq/hcli_23_005_02.html)。
