A Markdown table generator can create the pipes and separator row, but you still need to review the content. Keep cells short, give each column a clear heading, and use a list if a cell needs several sentences.
Preview the table on both wide and narrow screens. Literal pipe characters in cell text may need escaping, and line breaks can render differently across Markdown implementations. Check alignment and whether readers can understand each row without relying on color.
The rendered table is the final test, not the raw syntax.
