📝 Markdown table generator

Easily create Markdown tables. Supports specifying the number of rows and columns, setting the alignment of each column, and adding and deleting rows and columns. Real-time previews allow you to check your work as you go.

Number of columns: 1
Rows (data):

Usage and Application Examples

  • Write a list of specifications and a table of API specifications in README.md on GitHub
  • Create a comparison table or parameter list in a technical blog or Qiita article
  • Set the alignment (left-aligned, center-aligned, or right-aligned) for each column to make the table easy to read.
  • Flexibly adjust table structure by freely adding and deleting rows and columns

What is Markdown Table Generator?

Markdown Table Generator is a browser-based tool that simplifies creating perfectly formatted Markdown tables. Instead of manually typing pipes and dashes, you specify your desired row and column counts, set individual column alignments (left, center, or right), and generate ready-to-use table syntax instantly. This tool eliminates formatting errors and saves time when documenting technical information, creating README files, or organizing data in code repositories.

How to Use

Enter the number of rows and columns you need in the input fields. For each column, select your preferred alignment: left-aligned for text, center for headers, or right-aligned for numerical data. The generator displays a visual preview of your table structure. Add your content by clicking on cells and typing directly into the preview. Download the generated Markdown syntax or copy it directly to your clipboard. Modify column alignment anytime and regenerate the syntax instantly without losing your content.

Use Cases

Documentation writers use this tool for multiple scenarios:
• Creating API reference tables and feature comparison matrices
• Organizing README files with installation options or platform compatibility
• Structuring test results, benchmarks, and version histories
• Building project management tables for timelines and resource allocation
• Formatting course schedules, rubrics, and assignment guidelines
• Presenting product comparisons and pricing tiers

Tips & Insights

Right-aligned columns work best for numerical data, enabling easy visual comparison. Center alignment suits header rows and categorical data. Left alignment accommodates longer text entries comfortably. Markdown tables render consistently across all platforms—GitHub, GitLab, Slack, and Notion all interpret them identically. Keep column headers concise but descriptive. Use separator rows to organize complex data logically. Markdown tables generate valid HTML when processed, making them future-proof for content migration.

Frequently Asked Questions

What are Markdown tables?

Markdown tables are a syntax for describing tabular data using pipes (|) and hyphens (-), available on GitHub, Qiita, Zenn, and many other platforms to create easy-to-read tables in README.md and documentation.

How is the column alignment set up?

The alignment buttons under the header of each column allow you to select left-align, center-align, or right-align, as expressed in Markdown syntax by the position of the colon (:) on the separator line. Left-aligned is ":---", centered is ":---:", and right-aligned is "---:".

Can I add or delete rows or columns in the middle of a row or column?

Yes, you can add with the "Add Column" and "Add Row" buttons, and you can delete unwanted matrices with the delete button for each row and column. The operation is reflected while existing data is retained.

Where can I use the generated Markdown?

Available on GitHub, GitLab, Bitbucket, Qiita, Zenn, Notion, HackMD, and other Markdown-enabled services, it is ideal for organizing and displaying tabular data in README files, wikis, blog posts, etc.

How do you check the preview?

A preview of the rendered table appears in real time below the Markdown output area. Each time you edit the cell contents, the preview is automatically updated so you can check the final look and feel as you work.

What if the copied Markdown does not display well?

Markdown tables must have a header line, a separator line, and a data line. The table must also have blank lines before and after the table to be rendered correctly. The tool automatically generates the correct syntax, so you can use the copied code as is.

Can I customize the table borders and styling?

The generator creates standard Markdown table syntax, which displays borders and alignment based on your Markdown viewer or website platform. When you export or view the table in different platforms (like GitHub or web rendering), border styles may vary based on that platform's CSS styling.

What's the maximum number of rows and columns I can create?

The tool allows you to specify any reasonable number of rows and columns, though very large tables (100+ rows or 20+ columns) may become difficult to manage. For practical purposes, most Markdown tables work best with 10-20 rows and 3-10 columns.

Can I convert my Markdown table to HTML format?

You can copy the Markdown table and use an online Markdown-to-HTML converter, or paste it into the Markdown Editor tool which has an HTML export feature. Most Markdown renderers will automatically convert your table to proper HTML when displayed on web pages.

Can I add colors or highlight cells in a Markdown table?

Pure Markdown doesn't support cell colors or backgrounds, but you can use HTML directly within Markdown cells for advanced styling. Some platforms like GitHub extend Markdown with limited styling, but for rich formatting, you'd typically export to HTML or use a different format.

What special characters need to be escaped or avoided in table cells?

The pipe character (|) must be escaped using a backslash (\|) since it's the Markdown table delimiter. Line breaks within cells may not render properly in all platforms, so it's best to keep cell content on single lines for compatibility.

Can I import data from a CSV or Excel file to create a table?

This tool generates tables from scratch by setting row/column counts, but you can copy-paste CSV data and manually format it as a table. Some online tools can convert between CSV and Markdown format if you need that workflow.
