The API already supports table calculation filters via `filters.tableCalculations`, but the SDK has no way to reference table calculations in `.filter()` calls.\n\n## Root cause\n\nThe SDK's filter system is built exclusively around `Dimension` objects:\n- `DimensionFilter` in `filter.py` validates that `field` is a `Dimension` instance\n- `CompositeFilter.to_dict()` serializes all filters under the `\"dimensions\"` key\n- There is no `TableCalculationFilter` class or `\"tableCalculations\"` serialization path\n\n## Proposed solution\n\nAdd a filter type for table calculations that serializes under `filters.tableCalculations` in the API payload, similar to how `DimensionFilter` serializes under `filters.dimensions`.\n","author":{"url":"https://github.com/jpetey75","@type":"Person","name":"jpetey75"},"datePublished":"2026-06-12T20:53:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/21/python-sdk/issues/21"}
