See this question for more details.

Answer 2

You can also use tabs if that will help line up things

Explanation:

This is for more of a table look, but @Stephan V. cleaned up a table for me using the tab character ">".

For example:

This has no tabs

">"This will have one tab

This now has one tab

This has two

And so on...

The example of the table is in this question - hit edit to see the use of the tabs:
