This commit adds table alignment in markdown which allows the following
for tables:
right aligned | center aligned | left aligned
-: | :-: | :-
a | b | c
This will output a table in the following format:
right aligned | center aligned | left aligned
a | b | c
If headings are set, the header line (the line immediately below the
headings is ignored when calculating the max width for the columns.
All lines are trimmed of additional whitespace leading and trailing
whitespace to prevent tables that look like:
right aligned | center aligned | left aligned
------------: | :------------: | :-
a | b | c
right aligned | center aligned | left aligned
a | b | c
