It depends on the font you are using: most are proportional
which means that all characters are not the same width; an "I" is narrower than a "W" for example.
Non-proportional fonts all have characters with the same widths:
So one way to do what you want is to change the font - but that can look ugly.
Instead, consider using a table instead: W3Schools HTML tables
Tablet autocorrect :sigh:[/edit]
