Markdown Table Generator: Build Tables Visually for GitHub and Documentation
Writing Markdown tables by hand is tedious and error-prone. Counting pipes, keeping columns aligned, and remembering the separator row syntax slows you down every time.
Our Markdown Table Generator gives you a spreadsheet-like editor where you click, type, and get perfectly formatted Markdown table syntax instantly. Set column alignments per column, resize your table dynamically, and see a live HTML preview - all without writing a single character of table syntax.
Markdown table syntax uses pipe characters to separate cells:
Where Markdown Tables Are Used
GitHub READMEs - Comparison tables, feature lists, API parameter documentation
Documentation sites - MkDocs, Docusaurus, Jekyll, Hugo all render Markdown tables
Notion & Obsidian - Both support Markdown table import and rendering
Stack Overflow - Stack Overflow supports a subset of Markdown including tables in answers
Slack and Discord - Some integrations and bots render Markdown table formatting
Column Alignment Options
Markdown supports three alignment modes per column, set in the separator row:
Left align (:---) - Default. Text starts at the left edge, ideal for text content
Center align (:---:) - Text is centered, ideal for status columns and icons
Right align (---:) - Numbers and monetary values align from the right for easy comparison
Practical Examples
API documentation table
- 1.Columns: Parameter, Type, Required, Description
- 2.Alignment: Left, Center, Center, Left
- 3.Use case: GitHub README or docs site API reference
Feature comparison table
- 1.Columns: Feature, Free Plan, Pro Plan, Enterprise
- 2.Alignment: Left, Center, Center, Center
- 3.Use case: SaaS pricing page or README comparison
Frequently Asked Questions
What is a Markdown table?
A Markdown table is a way to organize data into rows and columns using pipe characters (|) and dashes (-). It is supported by GitHub, GitLab, Notion, Obsidian, many static site generators, and most Markdown renderers.
How do I use the generated table?
Copy the Markdown output and paste it directly into your GitHub README.md, documentation file, Notion page, or any Markdown editor. The table will render with proper formatting automatically.
How do column alignments work in Markdown?
Alignment is specified in the separator row (second row) using colons. Left align uses :--- , right align uses ---: , and center align uses :---: . The tool generates this automatically based on your alignment settings.
What is the maximum table size?
The tool supports up to 15 rows and 8 columns. For very large tables, we recommend using a spreadsheet tool and exporting to CSV, then converting to Markdown.
Does the table support Markdown formatting inside cells?
Yes, you can type Markdown formatting like **bold**, *italic*, or `code` inside the cell inputs and it will be included in the output. However, the visual editor does not render cell-level formatting.
Can I use this for GitHub READMEs?
Yes. GitHub Flavored Markdown (GFM) fully supports the table syntax this tool generates. The output is compatible with GitHub, GitLab, Bitbucket, and all major code hosting platforms.
Is the live preview accurate?
The live preview renders the Markdown table as HTML, which closely matches how it will appear in most Markdown renderers. Minor style differences may exist between different platforms.
Can I add more rows and columns later?
Yes. Use the + and - buttons next to Rows and Columns to dynamically add or remove rows and columns. Existing cell content is preserved when you add new rows or columns.
