## Which issue does this PR close? - Closes #21304. ## Rationale for this change The existing custom table providers doc was minimal and thanks to @timsaucer this [blog post](https://datafusion.apache.org/blog/2026/03/31/writing-table-providers/) covers the same topic with much more depth. Thus, @alamb opened the issue for incorporating blog post. ## What changes are included in this PR? I've replaced content with blog post with some changes: - fix several broken URLs (e.g. ParquetSource url was broken) - made some examples compilable - fix ExecutionPlan api - kept table constraints and `using your table provider` sections - remove acknowledgements and get involved ## Are these changes tested? Ran cargo test -p datafusion --doc custom_table_providers — 3 passed, 7 ignored. Then build with `docs/README.md` instructions and ss for docs: <img width="1353" height="948" alt="image" src="https://github.com/user-attachments/assets/7bbac01e-bab2-472e-b5f0-0661ead0249b"; /> <img width="1358" height="954" alt="image" src="https://github.com/user-attachments/assets/2f7d1faa-da56-436a-99b1-53afb0073c51"; /> ## Are there any user-facing changes? documentation only -- This is an automated message from the Apache Git Service.
