Result

This page opens the table builder with a three-column sample grid - Item, Qty and Price - already set to three different alignments, so you can see left, center and right column alignment side by side in one table.

GitHub-flavored Markdown marks column alignment in the separator row: a leading colon means left (:---), colons on both ends mean center (:---:), and a trailing colon means right (---:). The alignment select above each column in this grid writes that syntax for you, so there is no separator row to hand-edit.

Change any alignment dropdown to see the separator row update immediately, or edit the sample cells and add your own columns - the output stays a correctly padded, properly aligned GFM table throughout.

Accepted Formats & Rules

  • Editable spreadsheet-like grid with add/remove column and add/remove row controls.
  • Left/center/right alignment picker per column, mapped to the GFM separator row.
  • Paste CSV or TSV to import rows straight from Excel, Google Sheets or a .csv file, with a proper quoted-field parser.
  • Live output textarea with column-width padding and a one-click copy button.

Key Benefits

✓ Click any cell and type - there is nothing to paste or format first, the grid itself is the input.
✓ The GFM markdown output below updates on every keystroke, already padded to readable column widths.
✓ Per-column alignment sets the exact :---/:---:/---: separator syntax without memorizing it.

Use Cases

  • • Build a comparison table for a README cell by cell, adding a column mid-way when a reviewer asks for one more metric.
  • • Paste a small range copied from Google Sheets, fix a couple of typos right in the grid, and copy the padded GFM table into a GitHub issue.
  • • Set the price column to right-aligned and the name column to left-aligned so the rendered table reads cleanly in a wiki page.
