Format with tabs (tsv) or comma (csv) to copy into spreadsheet / office #49
Description
I sometimes want to copy a report into a tool that can store actual tables, but that does not accept markdown.
This could be Jira or an office or spreadsheet application.
Currently the easiest way to achieve that is to output as markdown with --md, then copy into a markdown-capable platform (like github), use "Preview", then copy + paste into the target application.
To make this easier, we could output with tabs as separators, or commas.
To support arbitrary strings, we would need to add quotes as in a true csv or tsv, if a table cell already contains a separator char (tab, comma).
(For now I am just putting this out here as a suggestion, if not more people ask for it, then there is no point to spend time on it.)
