I would like to suggest that a table/grid control be added to the markdown options, as it pains me to see people trying to show a sample portion of an excel document, and having it come out as a line of text.
Even if they knew enough formatting to put the data on different lines with a double space at the end, it would still be hard to get the columns to work out.
As of now, the only real solution is to insert an image, but this makes it harder for people to copy and test with on their machines.
Thoughts?
