Markdown tables are physically represented using dash - for to separate the header row from the content ones and pipe | for columns.

Column	Column
Cell	Cell

is produced by

Column | Column
------ | ------
Cell   | Cell  

You can also populate a table in any way you want -

Letter	Digit	Character
a	4	$
	365	(
b		^

That table's code:

Letter | Digit | Character
------ | ------|----------
a      | 4     | $
       | 365   | (
b      |       | ^  

Markdown ignores spacing. The same table could be written like this:

Letter|Digit|Character
---|---|---
a|4|$
 |365|(
b| |^  

and still display the same:

Letter	Digit	Character
a	4	$
	365	(
b		^

NOTE: if you need a void column you must add a space between the pipes

As you can see, the code of the table does not need to represent the spacing of the table - that is accomplished within the markdown.

You should want to align the content of a table. All you have to do is add some colons in this way:

Aligning the column:

: is used to align a column. Left align is the standard.

Column | Column | Column
:----- | :----: | -----:
Left   | Center | Right
align  | align  | align

Column	Column	Column
Left	Center	Right
align	align	align

If you want to use a pipe character (|) in the content of a cell you'll need to escape it with a backslash.

Column | Column
------ | ------
\| Cell \|| \| Cell \|  

This results in the following table:

Column	Column
| Cell |	| Cell |
