Why a visual Markdown table?
Markdown tables are great to read in source form when they're small, but writing them by hand is tedious for anything bigger than a 3×3 grid. The pipe characters and dash separators have to line up, alignment colons are easy to forget, and column widths shift on every edit. A visual editor sidesteps the alignment dance entirely.
This tool lets you edit a table in a familiar grid, then emits clean Markdown source on the right. The output is GFM-compatible (GitHub, GitLab, BitBucket, most Markdown processors). Column widths are auto-padded for readability in the source. The colons in the separator row encode left/center/right alignment as the spec dictates.
How to use this tool
- Edit cells directly in the grid. The first row is the header and stays bold. Click '+ Add row' or '+ Add column' to grow the table; use × to remove.
- Pick a per-column alignment using the dropdown in each header cell. Left is the default; center is good for short labels; right is best for numeric data.
- The Markdown source updates live in the output pane. Click Copy to grab it and paste into your README, blog post, ticket description, or any Markdown editor.
Frequently asked questions
Which Markdown flavours support tables?
GitHub-Flavored Markdown (GFM), CommonMark with the tables extension, GitLab Flavored Markdown, BitBucket, Bear, Notion (limited), and most blog engines. Tables are not in the original Markdown spec, so very old or strict CommonMark renderers may not parse them.
How do I align columns?
The colons in the separator row do it: ':---' for left, ':---:' for center, '---:' for right. This generator emits the right pattern based on the alignment dropdown — you don't have to remember.
Can I include Markdown formatting inside cells?
Yes. **bold**, *italic*, `code`, [links](https://example.com), even inline HTML render correctly inside table cells. Newlines inside cells need to be escaped as <br> since the cell itself is a single line in source.
What's the largest table I should use?
Markdown tables work great up to ~10 columns and ~30 rows. Beyond that, readability suffers in both rendered and source form. For larger datasets, prefer CSV (with a renderer) or an actual data table in HTML.
Are my edits saved?
No. Everything is in your browser's memory only. Refresh the page and you start fresh. This is intentional — the tool stays simple and your data stays private.
Common use cases
Where a quick visual table beats writing one by hand.
Comparison tables in a README
Open-source READMEs love tables comparing features, plans, or supported platforms. Build the table here, copy the Markdown into the README — much faster than aligning pipes manually.
Documentation pricing or feature pages
Three-plan SaaS pricing layouts work well as Markdown tables when your docs site renders Markdown. Centered columns for prices, left-aligned for feature names.
Issue and PR descriptions
GitHub issue and PR bodies render Markdown. Tables are perfect for 'before/after' comparisons, environment matrices, or test result summaries.
Status reports and weekly summaries
Status: 'In Progress / Done / Blocked' columns, owner column, due date column. Build once, copy into Slack/Notion/wherever your team posts updates.
Tips and shortcuts
Habits that make Markdown tables actually pleasant.
Right-align numbers
Decimal points and digit counts read best when right-aligned. The brain compares 12.50 and 0.99 instantly when stacked vs. left-aligned where '1' under '0' breaks the eye-saccade.
Keep cell content short
Markdown tables don't wrap cell content visually in most renderers — long cells produce horizontal scrollbars. If a cell is longer than a tweet, refactor to a definition list or a numbered list.
Use HTML tables for advanced needs
Cell merging, multi-line cells, or rowspans are not in the Markdown table spec. When you need them, fall back to plain HTML <table> markup — it works fine inside Markdown documents.
Don't forget the empty header row
Some renderers (older Pandoc, strict CommonMark) require the header row to be present even if empty. If your table renders as text, check that you have at least the |---| separator row directly below your header line.
