colspan differences with GitHub Flavored Markdown & PHP Markdown Extra

Quick question... Why does MMD chose to treat multiple pipes in a row as a colspan rather than as blank cells, contra PHP Markdown Extra & GitHub flavored Markdown?

I completely sympathize with Penney's earlier comment, "*perhaps a slight exaggeration, but there are almost as many syntaxes for tables as the original Markdown has for all of its features... ;)*", which is right on the money, so this isn't a question about which is "better". ;^) Rather, I saw that MMD table syntax was based loosely on PHP MD Extra, so I'm guessing the compatibility break was intentional.

Fwiw, I do think I prefer MMD... If you need an empty cell, you add a space and you're done, and that behaves the same in all three of these MD flavors. Mostly just curious why the break from other table formats for colspans.

    It's not a question of a difference in interpretation as much as it is that I added features to PHP Markdown Extra's more simplistic table syntax. PHP ME doesn't have a concept of multiple pipes in a row, so they are just empty cells.

    GFM came much later, so I can't speak to it.
