Cell rendering
All 25 scenarios hold
The reporter publishes the value a row ran with, and not the text of the cell. It therefore writes every value back out, and each format writes that value back the way that format can.
Where the formats differ, the rules below show all three side by side. Markdown and AsciiDoc come first. Both are plain text, and both answer most questions alike. HTML comes last, because its answer is markup and always the longest.
A collection does not fit that shape. Markdown alone puts a whole collection inside a table cell. AsciiDoc opens a bulleted block or a description list below the cell. HTML nests list markup inside the cell. A table can hold neither of those, so the notation rule belongs to markdown alone.
