Haystack 2 Table Q/A

[sohanasarah]

I have tabular data that I want to use with a LLM using Ollama. In the previous version of Haystack, there was a table reader component for table Q/A. Can I use something similar in Haystack 2 to interpret my tabular data and then feed the result to the LLM?

Hi @sohanasarah supporting Table QA in Haystack 2.0 is on our roadmap but it is currently not implemented yet. #6674
A Document in Haystack 2.0 at the moment has a dataframe to store any tabular data but there is no TableReader or sth similar yet.

haystack/haystack/dataclasses/document.py

Line 55 in 22e9def

:param dataframe: Pandas dataframe with the document's content, if the document contains tabular data.

I get this error when I try to store a data frame as a Document and write it to the document store. Do you have any suggestions on how to resolve it?

This is my code:

def csv_to_dataframe(filename):
    df = pd.read_csv(filename)
    df = df[df["Site"].notna()]
    df = df.sort_values("Site")
    return df

table = csv_to_dataframe(f"./cell_status.csv")

docs = Document(content=table)

document_store = InMemoryDocumentStore()
document_store.write_documents(docs)

You are passing a single document instead of a list
