Preserve row and column meaning
Tables encode relationships through headings, units, row labels and sometimes merged cells. A flat sequence of words can lose those relationships. Decide how the system will retain the structure and how answers will identify the relevant row and column. Evaluate numerical questions separately from general text questions, since their failure modes differ.
Worked example
Illustrative scenario; not a claim of measured client results.
For a table listing support hours by service tier, preserve the tier label, timezone and any footnote describing holidays. An answer quoting only a number of hours can be wrong even if that number appears in the document. Test neighboring rows and similar tier names to catch accidental cross-row combinations.
Checks, limitations and next decisions
If answers mix values, inspect extraction and context assembly before adjusting style instructions. Consider a structured lookup for exact tabular data when that is more dependable than free-form interpretation. Cite the relevant table and explain units in the response. Do not let a plausible summary conceal missing conditions or arithmetic that has not been independently validated.
A practical starting point
Work through these checks in order. Use the results to decide what needs to change in your own workflow.
- Preserve column names and row identifiers during extraction.
- Test questions involving comparisons and numerical values.
- Use structured queries where exact lookup is more reliable than narrative retrieval.
A mistake to avoid
Do not ask a language model to infer missing table structure from ambiguous fragments.
How to check progress
Evaluate exact-value accuracy and whether units and qualifiers remain attached.
