The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

Pipe rows are parsed, padding is recalculated to the widest displayed cell, and a normalized separator row is written. Cell pipes and alignment markers are escaped or retained so the table remains parseable.

  • Left alignment and one-space padding match common GFM style.
  • Formatting changes spacing only.

Input
											| Name | Age |

| Bob | 25 |
Output
												| Name  | Age |
| :---- | :-- |
| Alice | 30  |
| Bob   | 25  |

When to use this

README tables, release notes, and generated documentation normalize with this pass.

Edge cases

  • A pipe inside a code span can be mistaken for a separator by line parsing.
  • Short rows are padded while extra cells remain separate.
  • A malformed separator may be treated as data.
