What are markdown tables?

Markdown tables are a lightweight syntax for creating tabular data in plain text. They use pipes (|) to separate columns and hyphens (-) for the header separator row. Supported by GitHub, GitLab, Reddit, and most markdown renderers.

How it works

A markdown table has a header row, a separator row, and data rows. The separator row can include colons to control alignment: :--- for left, :--: for center, and ---: for right. This tool generates clean, padded output where columns are aligned with spaces for readability in source form.

How to use this tool

• Edit headers and cells inline — the markdown output updates in real time
• Add or remove rows and columns with the toolbar buttons or the side controls
• Click the alignment icon on each column header to cycle between left, center, and right alignment
• Paste CSV or tab-separated data into any cell to auto-expand the table
• Copy the generated markdown with the Copy button

Common use cases

• Creating tables for GitHub README files, issues, and pull request descriptions
• Converting CSV data into clean markdown for documentation
• Building comparison tables for blog posts or wikis
• Formatting API parameter lists or configuration references
