Create a markdown table export

[numeredev]

DESCRIPTION

What does your feature request improve on? Please describe. It is possible to export a table to many formats but not into markdown, which is tedious if you want to embed a larger table into such a document type.

Describe the solution you'd like Create a markdown table export either via supporting export TABLE() -file=FILE.md or via a menu option within the table viewer or possibly even both.

Additional context Add any other context or screenshots about the feature request here.

ANALYSIS

Should not be too hard. It might be reasonable to achieve it via creating a MarkDown implementation for the GenericFile class, which can only export but not (necessary) load. Adding the corresponding file masks to be able to select the markdown export is kind of straightforward.
