About this tool
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.
Example. Typing Name and Age into the header cells emits a GitHub-flavored table that starts with a header row Name and Age and a separator row of dashes.
Limit. The grid refuses to grow past 20 columns or 100 rows including the header.
