When you are looking at table in the bottom panel, it would be nice if you changed the columns and rows ever so slightly. Instead of making the single dash continuous but made the two horizontal lines continuous instead, then, when you copy and paste this into a Markdown file, it will format it properly

Example

from...

[dbo].[foo]

Column | Datatype | Computed value

Id | int |

...

to...

[dbo].[foo]

Column | Datatype | Computed value
----------------------|-------------------|-------
Id | int |
