How it works
The Markdown Table Generator provides a visual spreadsheet-style grid where you set the number of rows and columns, type your content into each cell, and the tool continuously updates the Markdown table syntax in the output panel. There is no need to remember pipe and dash syntax — the tool handles all formatting automatically.
Column alignment (left, center, right) can be set per column using alignment toggles. The generator inserts the correct colon notation in the separator row (:---, :---:, ---:) so the table renders correctly in GitHub, GitLab, Notion, Obsidian, and any other Markdown processor that supports GFM tables.
Once your table is ready, click the copy button to grab the raw Markdown. Paste it directly into a README, wiki page, pull-request description, or documentation file. The tool runs entirely in your browser, so nothing you type is sent to a server.
Worked example
Create a feature comparison table for a README
- Set rows to 4 and columns to 3.
- Fill the header row: 'Feature', 'Free Plan', 'Pro Plan'.
- Fill the data rows with feature names and Yes/No values.
- Set the 'Free Plan' and 'Pro Plan' columns to center alignment.
- Click 'Copy Markdown' and paste into your README.md file.

Common mistakes to avoid
- Leaving cells empty in the header row — most Markdown processors require all header cells to have content for the table to render correctly.
- Pasting content that contains pipe characters '|' inside a cell without escaping them, which breaks the table structure.
- Expecting the table to render in plain-text email or older wikis that do not support GFM tables.
Key terms
- GFM (GitHub Flavored Markdown)
- A Markdown dialect supported by GitHub and many other platforms that adds tables, task lists, and strikethrough to standard Markdown.
- Separator row
- The second row of a Markdown table, made of dashes and colons, that defines column alignment and signals that the first row is a header.
Frequently asked questions
- Can I paste this into GitHub?
