Struggling with a specific table view implementation

[dmitresco]

Hey people! I just recently started exploring the amazing library. I'm a bit stuck with my current task for implementing a specific table view.
Can you maybe direct me how should I build data and related columns object. So the most important thing is how to make few first common cells (Product) and nested warehouses
The design:

Raw data (I can transform it if necessary):

[
    {
      "dim_id": "SKU_0",
      "dim_type": "sku",
      "dim_value": "SKU_0_NAME",
      "warehouse": [
        {
          "dim_id": "56698f8a-e7fc-494e-9951-fcc931e5c3d7",
          "dim_type": "warehouse",
          "dim_value": "WAREHOUSE_0",
          "data": [
            {
            "as_per": "2024-07-13",
            "baseline_forecast": "100.00",
            "campaign_increase": "0.00",
            "effective_forecast": "100.00",
            "effective_forecast_user_change": null
          },
          {
            "as_per": "2024-07-14",
            "baseline_forecast": "100.00",
            "campaign_increase": "0.00",
            "effective_forecast": "100.00",
            "effective_forecast_user_change": null
          },
          ],
        },
        {
          "dim_id": "3f8fd127-7de1-457a-8a70-f3d493cb78e0",
          "dim_type": "warehouse",
          "dim_value": "WAREHOUSE_1",
          "data": [
            {
            "as_per": "2024-07-13",
            "baseline_forecast": "100.00",
            "campaign_increase": "0.00",
            "effective_forecast": "100.00",
            "effective_forecast_user_change": null
          },
          {
            "as_per": "2024-07-14",
            "baseline_forecast": "100.00",
            "campaign_increase": "0.00",
            "effective_forecast": "100.00",
            "effective_forecast_user_change": null
          },
          ],
        }
      ]
    },
    {
      "dim_id": "SKU_1",
      "dim_type": "sku",

            "effective_forecast_user_change": null
          },
          ],
        }
      ],
    },
  ]

One of the few things that TanStack Table and MRT don't really have considerations for is row and column spanning (outside of header groups)

[smartdeepp]

So are there any plans to get this row/column span feature in upcoming releases or future discussion?

[KevinVandy]

I probably won't be the one who spends the time to work on it. Maybe someone will contribute it to TanStack Table in the future.
