Is there a way I can provide it with additional context about columns (other than their headers) i.e., a column will either be “public” or “private”, 0 means no, 1 means yes, etc.?
This is interesting, out of curiosity were you planning to use our vector store index (which takes in unstructured data), or our structured index? (which takes in tabular data and allows you to run SQL-esque queries over it). For the latter, I've had a TODO to help add unstructured context to structured data
