Markdown Table Builder

Markdown tables are deceptively annoying to write by hand: the pipe-and-dash syntax (`| Header | --- |`) is unforgiving, alignment colons (`:---:`) are easy to forget, and getting the column widths to look clean in your editor takes obsessive tabbing. The Markdown Table Builder gives you a spreadsheet-style grid: type in the cells, click "Add row" or "Add column" as you need them, click each column header to cycle its alignment (default → left → center → right), and the GitHub-Flavored Markdown output regenerates on every keystroke. A live HTML preview shows you exactly how the table will render in GitHub, GitLab, Notion, Obsidian, Discord, and every other GFM-compatible target. There's also an "Import existing markdown table" panel so you can paste a table from somewhere else, edit it visually, and re-export — much faster than hand-editing raw markdown when you need to add a column or fix a typo deep in the middle. The whole tool runs in your browser; no upload, no account.
