How do I create a small table “in memory” from a node similar to “set” or so?
For example:
+-----------+--------+--------+
| City | Year | Amount |
+-----------+--------+--------+
| Barcelona | 2024 | 33 |
| Barcelona | 2027 | 88 |
| Barcelona | 2028 | 77 |
| Madrid | 2023 | 55 |
| Madrid | 2024 | 11 |
| Ibiza | 2025 | 22 |
+-----------+--------+--------+
So I can play with manually starting the workflow and see how a file is written?
