def markdown_table(step):
  # The text summary can also contain Markdown, including Markdown
  # tables. Markdown tables look like this:
  #
  #     | hello | there |
  #     |-------|-------|
  #     | this  | is    |
  #     | a     | table |
  #
  # The leading and trailing pipes in each row are optional, and the text
  # doesn't actually have to be neatly aligned, so we can create these
  # pretty easily. Let's do so.
