В PostgreSQL у меня есть таблица с такими данными. Как вы можете заметить, здесь хранится информация об иерархических отношениях между отделами. Например, Google является родителем Google Play, Google Analytics является родителем Google Finance.
| ORGANIZATION_ID | ORGANIZATION_NAME | ORGANIZATION_RANG | PARENT_ORGANIZATION_ID | PRODUCT_PERCENT |
|-----------------|-------------------|-------------------|------------------------|-----------------|
| 1 | Google | 1 | | 50 |
| 2 | Google Play | 2 | 1 | 30 |
| 3 | Google News | 2 | 1 | 25 |
| 4 | Google Analytics | 2 | 1 | 77 |
| 5 | Google Finance | 3 | 4 | 88 |
| 6 | Apple | 1 | | 35 |
| 7 | Apple Pay | 2 | 6 | 73 |
В моем приложении Go я делаю SQL-запрос к этой таблице. Я хочу сгенерировать такое JSON, которое затем могу отправить клиентскому приложению:

ВОПРОС : Может ли кто-нибудь помочь с логикой формирования HTML-тегов и значений rowspan и colspan ?! Я очень запутался и мне нужен совет.
P.S. С помощью этого файла JSON я могу создать такую HTML-таблицу в клиентском приложении:
HTML-разметка таблицы выглядит так:
<table>
<tr>
<td rowspan="5">Google</td>
<td colspan="2">Google</td>
<td>50</td>
</tr>
<tr>
<td colspan="2">Google Play</td>
<td>30</td>
</tr>
<tr>
<td colspan="2">Google News</td>
<td>25</td>
</tr>
<tr>
<td rowspan="2">Google Analytics</td>
<td>Google Analytics</td>
<td>77</td>
</tr>
<tr>
<td>Google Finance</td>
<td>88</td>
</tr>
<tr>
<td rowspan="2">Apple</td>
<td colspan="2">Apple</td>
<td>35</td>
</tr>
<tr>
<td colspan="2">Apple Pay</td>
<td>73</td>
</tr>
</table>
