Is this GitHub-flavored Markdown?

Yes. The output uses the standard pipe-and-dash table syntax with colon alignment markers that GitHub, GitLab and most Markdown renderers understand.

How does column alignment work?

The divider row uses colons — left puts no colon, center wraps the dashes in colons, and right adds a trailing colon, matching the GitHub-flavored Markdown spec.

Is my data uploaded anywhere?

No. The table is built entirely in your browser with JavaScript, so your content never leaves your device.

How do I align a column left, center or right in Markdown?

Alignment lives in the separator row of dashes. Plain dashes (---) are left-aligned, a leading and trailing colon (:---:) is centered, and a trailing colon only (---:) is right-aligned. This generator writes those markers for you when you pick an alignment per column.

Can I add or remove rows and columns?

Yes. Set the number of columns, name each header, and add or remove rows in the grid as you go. The Markdown output regenerates live every time you change the structure or a cell value.

Will the output render on GitHub and GitLab?

Yes. The output is standard GitHub Flavored Markdown pipe tables, which GitHub, GitLab, Bitbucket and most static-site generators and Markdown editors render natively. No HTML is used.

Why is the output padded with extra spaces?

The cells are padded so each column lines up in the raw text. This is purely cosmetic — Markdown renderers ignore the extra spaces — but it keeps the source readable and diff-friendly in a README or pull request.

Markdown Table Generator

Writing Markdown tables by hand is fiddly — counting pipes, matching dashes, lining up columns. This generator turns a simple grid into clean GitHub Flavored Markdown you can paste straight into a README, GitHub issue, wiki page or any Markdown document, with per-column alignment handled for you.

How it works

Set the number of columns and name each header, then choose left, center or right alignment per column and fill in the cells. The tool builds the output as:

a header row of cell values between pipes,
a separator row of dashes that also encodes alignment — --- (left), :---: (center) or ---: (right),
one data row per grid row.

Cells are space-padded so the columns line up in the raw text; renderers ignore the padding, but it keeps the source readable. The Markdown updates live and a Copy button puts it on your clipboard.

Example

Two columns, the second right-aligned:

| Item   | Price |
| :----- | ----: |
| Coffee |  3.50 |
| Tea    |  2.80 |

Alignment	Separator markup
Left	`:---` or `---`
Center	`:---:`
Right	`---:`

Everything runs locally in your browser — nothing is uploaded, so it is safe for private notes and internal documentation.
