Merged Cells in Tables

[sirinath]

One feature many markdown table syntax lacks is merged cells in tables.

There are a number of limitations to the tables we currently support, including:

• no rowspans
• no colspans
• contents of a cell must fit on one line

There are some useful discussions of table syntax ideas at talk.comonmark.org, but in general this is a tough issue. I'm tempted to support something like reStructuredText's list tables for a more general format.

If a more powerful representation is introduced, I hope it will be able to express the appearance of "periodic table of the elements".

For reference, list tables are specifically the subject of #27.
