Markdown Table Generator
Markdown Table Generator creates placeholder headers named Column 1, Column 2, and so on, a dash separator row, and one empty data row. The column count has a minimum of one but no explicit upper cap. It does not populate data, choose alignment, escape content, or verify whether the destination renderer supports pipe tables.

Three placeholder headers, three --- separator cells, and one empty row.
Pipe tables are a Markdown extension
Many renderers recognize pipes and a header-separator row, but tables are not part of core CommonMark and extension details differ.
How it works
Enter the column count. The tool creates numbered header labels and joins header, separator, and blank cells with pipes.
Key concepts
A template is not structured data
Headers and rows still need meaningful content.
Wide tables degrade on small screens
Horizontal layout should be tested in the target renderer.
When to use it
- Start a small pipe table.
- Avoid manually counting separators.
- Create a blank template for later editing.
When not to use it
- Do not expect accessibility headers or captions.
- Do not generate extremely wide tables without reviewing usability.
- Do not assume every Markdown environment renders tables.
Worked examples
Three columns
- Input
3- Expected output
| Column 1 | Column 2 | Column 3 | …
Default-style placeholders are generated.
One column
- Input
1- Expected output
A single-column table
The minimum is one.
Invalid count
- Input
Non-number- Expected output
Three columns
The implementation falls back to three.
Common mistakes
Leaving placeholder headings
They convey no real column meaning. Correction: Replace each with a descriptive header.
Expecting alignment
No colon markers are generated. Correction: Add :---, ---:, or :---: manually.
Creating excessive columns
There is no explicit maximum. Correction: Choose a readable layout.
Best practices
- Use meaningful headers.
- Keep tables narrow.
- Test responsive rendering and screen-reader behavior.
