Markdown table generator

Why Markdown tables are fiddly

A Markdown table is just rows of text divided by pipe (|) characters, with a separator line under the header. That's simple in theory, but hand-writing one means counting pipes, keeping every row the same column count, and getting the separator line exactly right — and a single missing pipe silently breaks the whole table. Editing a visual grid instead and letting the tool emit the syntax removes all of that friction, especially once a table grows past a few columns.

Column alignment

Alignment lives in the separator row, encoded with colons: :--- for left, :---: for centre and ---: for right. The per-column dropdowns set these for you. It's the standard GitHub-Flavored Markdown form, so the same output renders correctly on GitHub, GitLab, and most static-site and docs renderers — numbers right-aligned, labels left, whatever you choose.

Pipes and line breaks in cells

The other classic trap is content that collides with the syntax. A literal | inside a cell would end the column early, so this generator escapes it to \| automatically; line breaks within a cell are flattened to spaces, since a Markdown table row must stay on one line. The result is valid no matter what you type. Paste the output straight into a README, an issue or a docs page — or, if you'd rather author in prose and convert, see the Markdown to HTML converter.
