Create Column

Add a new column to a sheet. Non-text columns will generate cells for all existing rows. Requests are scoped to the workspace associated with the API key; table, sheet, column, cell, operation, and version IDs must belong to that workspace.

POST /api/public/v2/tables/{table_id}/sheets/{sheet_id}/columns

Add a new column to a sheet. For non-text columns, cells for all existing rows are created with stale status and queued for computation.

Use dependencies to declare which other columns this column’s config references. PromptLayer enforces a DAG (no cycles allowed) and uses the dependency graph to propagate staleness when upstream cells change.

Creating a column creates a new sheet version. The response returns version, the current sheet version count after the column is added.
