What does the alignment option do?

It sets the column alignment in the Markdown separator row using :---, :---: or ---:, which most Markdown renderers use to left-, center- or right-align column content.

Why is the output padded with spaces?

Each cell is padded so the raw Markdown lines up in a monospace editor, making the table readable in source form. Rendered output is unaffected by the padding.

How do I separate columns in my input?

Choose the delimiter — comma, tab, semicolon or pipe — that matches your data. Each line becomes a table row and the first line is treated as the header.

Does the alignment change my data order?

No. Alignment only affects how text sits inside each cell when rendered. The order of your columns and rows is preserved exactly as entered.

Can different columns have different alignment?

The current tool applies one alignment to all columns. After generating, you can edit individual colons in the separator row if you need per-column alignment.

What if rows have unequal numbers of cells?

Shorter rows are padded with empty cells so the table stays rectangular and valid Markdown.

How to use Markdown Table Generator

The Markdown Table Generator builds neatly aligned, GitHub-ready Markdown tables from plain rows of data, right in your browser. Type or paste your rows using a delimiter of your choice, pick whether columns should be left-, center- or right-aligned, and the tool pads every cell so the raw Markdown lines up perfectly in a code editor while rendering as a clean table. It is the fastest way to hand-author a tidy table for a README, issue or documentation page without fiddling with pipes and dashes yourself.

Pick the delimiter that separates your columns.
Choose the column alignment — left, center or right.
Type or paste your rows, with the first row as the header.
Review the padded, aligned Markdown table in the output.
Copy the result and paste it into your document or repository.

Your data never leaves your device — 100% private processing.

How alignment works in Markdown tables

Markdown encodes column alignment in the separator row that sits between the header and the body. A plain run of dashes (---) means default (usually left) alignment, a colon on the left (:---) forces left alignment, colons on both sides (:---:) center the column, and a colon on the right (---:) right-aligns it. Most renderers, including GitHub, respect these markers when displaying the table. This generator writes the correct colon pattern for the alignment you choose, so the rendered table matches your intent. Note that alignment applies to how content sits within each cell when displayed; it does not change the order or content of your data.

Markdown alignment markers
Separator	Alignment
---	Default (left)
:---	Left
:---:	Center
---:	Right

Why padding makes Markdown easier to maintain

Markdown tables render identically whether or not the source is padded, but padded source is far easier for a human to read and edit. When each cell is padded to the width of its widest value, the pipe characters line up into clean vertical columns in your editor, so you can scan the data, spot a misplaced value, or add a row without miscounting columns. This generator computes the maximum width of every column and pads each cell accordingly, producing the kind of tidy, aligned source that experienced Markdown authors craft by hand. If you prefer compact output you can always collapse the spaces later, but starting from an aligned table makes ongoing maintenance much less error-prone.

Glossary

Separator row: The second row of a Markdown table, made of dashes and colons, that divides the header from the body and sets alignment.
Alignment marker: A colon placed in the separator row to left-, center- or right-align a column.
Padding: Extra spaces added to a cell so columns line up vertically in the raw Markdown source.
Header row: The first row of the table, which names each column.
Delimiter: The character used to separate columns in your input data.
