The practical starting point
A table is useful for comparing a small set of items across consistent attributes. It is less useful when cells contain unrelated paragraphs. For a service comparison, decide which questions each column answers and use the same interpretation in every row.
A workable next step
Give the table a clear description and identify its headers. Keep units and missing values explicit. Do not use colour alone to carry an important distinction. Review a narrow-screen view and ensure readers can still understand the relationships. If the comparison cannot be made consistently, separate reference sections may be a clearer format.
Keep in your notes
- Keep attributes consistent.
- Identify headers and units.
- Explain missing values.
