Paste a Markdown table into the markdown panel and it is drawn at once. Click a header to sort by that column, and click a cell to copy its value.
The design panel starts from a set of palettes, then sets colors and sizes part by part: page, table, title, header, row and highlight. The file panel keeps several projects, saves them as JSON, and writes the table out as an image or as a standalone HTML page that still sorts and copies.
