Markdown Table Builder
Build a Markdown table without counting pipes by hand. Set the number of rows and columns, pick an alignment, and paste your data as plain tab-separated values (one row per line). We compute column widths, pad cells to line up nicely in the source, and emit valid GitHub-Flavored Markdown — including the alignment row (`| :--- | ---: |` etc.). The first row of your data is treated as the header. A monospaced preview shows roughly how the table will render. Everything happens locally in your browser.
