Renderers

• toASCII(tree, { format }) — format is ASCIITableFormat.MySQL (default) or ASCIITableFormat.MarkdownLike.
• toHTML(tree) — <table> with colspan/rowspan; header, index and corner cells are wrapped in <b>.
• XLSX — see the XLSX page.

Tip

Writing your own renderer is easy — cells() walks the tree and yields every cell with its position and span, rows() groups cells into visual rows (one array per <tr>, ordered left-to-right; rows fully covered by rowspans are present but empty):

import { cells, rows } from "@json-table/core";

See tree-to-html source code to create your own renderer.
