Does the UnstructuredElementNodeParser take into account the title for a table that's above the table? For example, would it be able to figure out that a table is a Cash Flow Statement if the title of the table is "Cash Flow Statement" in the document

Hi everyone! I'm following this tutorial: https://www.youtube.com/watch?v=xT6JpDELKPg, but when I try to get_nodes_from_documents, I get a message saying, "LLM is explicitly disabled. Using MockLLM. Embeddings have been explicitly disabled. Using MockEmbedding." Also, when I extract the base nodes, no tables are being extracted. My code is exactly the same as in the tutorial. Is this expected behavior?

Hello, is there a way I can have my RAG system say where in the document it retrieved its answer from? The end goal would be to highlight exactly in the document where the answer was retreived, so I'm trying to understand how this could be accomplished
