Support for Markdown row-/colspan

I need support for table row-/colspan in a table in Markdown.
One solution provided here seems to be plugins. But I do not find any plugin for grav supporting this.

Good would be for example MultiMarkdown.

How can I implement this?

Hi there. I had similar issue and eventually had to relent and stick to HTML for colspans and table-styling with CSS. Markdown is simple, but when it comes to tables it seems overly-simple (probably why there are so many markdown 'variants' with tweaks to tables).

Someone is sure to correct me if I'm wrong, but I'm afraid you may need to use HTML for more complex table formatting at this time.

Yup, markdown is really not intended to support complex table handling. Any solution in markdown would probably end up more complicated than simply using HTML to display the table.
