How to structure a Markdown table for documentation
Tables are the clearest way to present structured, scannable data in repositories and developer docs. Unlike prose or bullet lists, they let readers compare several attributes at once.
Keep headers short
Header labels set column width. Keep them under about 15 characters (“Method”, not “HTTP Request Protocol Method”) to avoid awkward wrapping.
Align by data type
Text left (
:---), status badges centered (:---:), and numbers, prices and dates right (---:).Escape pipes in cells
A literal pipe, such as the TypeScript union
string | number, must be writtenstring \| numberor it splits the cell.
Alignment syntax quick reference
The second row of every Markdown table sets column alignment. Use this when adapting a template:
| Alignment | Delimiter | Result | Use for |
|---|---|---|---|
| Left (default) | | :--- | | Flush left | Names, descriptions, titles, code paths |
| Center | | :---: | | Centered | Status badges (✓ / ✗), booleans, short dates, types |
| Right | | ---: | | Flush right | Prices ($19), percentages (99.9%), sizes (10 MB) |

How do I use these Markdown table templates in GitHub READMEs?
All 50 templates follow strict GitHub Flavored Markdown (GFM) standards. Click "Copy" on any template card, or open the template with "Customize" to edit rows and column alignment in the built-in editor, then paste the Markdown into your README.md or pull request description.
Can I add or remove columns from a template?
Yes! Click "Customize" on any template card. The template page includes an interactive table editor where you can add, delete and rename columns, rearrange rows, change alignment (left, center, right), or import your own CSV data into the template structure.
Why do numeric columns align to the right in these templates?
Right-aligning numbers (using "---:") aligns decimal places and digit magnitudes vertically, making financial prices, metrics, and memory sizes dramatically easier for the human eye to scan and compare.
How do I add multiple lines or bullets inside a template cell?
Standard Markdown breaks if you press Enter inside a cell. To create multi-line cells or bulleted lists, use the HTML `<br>` tag (e.g. `• First item<br>• Second item`) which renders cleanly across GitHub, GitLab, Notion, and Obsidian.
Can I download all 50 templates at once for offline documentation?
Yes! Click the "Download all (.md)" button next to the search box to download a single, formatted markdown document containing all templates, code blocks, and descriptions ready to drop into your Obsidian vault or team wiki.
Are there any usage restrictions or licenses on these templates?
No. All templates in this library are 100% free and open-source under the MIT license. You can freely copy, modify, and distribute them in commercial software, SaaS products, open-source repositories, and academic papers without attribution.
