mathpix-markdown-it
Version:
Mathpix-markdown-it is an open source implementation of the mathpix-markdown spec written in Typescript. It relies on the following open source libraries: MathJax v3 (to render math with SVGs), markdown-it (for standard Markdown parsing)

/**
* Renders a table cell token into multiple parallel representations:
* HTML/text (`content`), TSV, CSV, Markdown (`tableMd`), and a "smoothed" variant
* used for DOCX/PPTX where line wrapping and block-like inline tokens matter.
*
* This function is recursive: inline children may contain nested tabular content.
*
* @param token - Cell token (or inline token) whose children form the cell content.
* @param isSubTable - True if the current token is being rendered inside a nested table context.
* @param options - Rendering options (DOCX/PPTX/markdown math settings).
* @param env - Markdown-it rendering environment.
* @param slf - Markdown-it renderer instance (must support renderInline).
* @returns Combined render outputs for this cell.
