It is very important for code readability and understanding to use the same coding style across all files of an application. It is even important to have the same coding style in all your source code.
Having the same coding style helps reading the code. And if you carefully select your coding style, you can even pinpoint coding errors simply because something look strange in the layout.
Of course, if you share your code among a team, like I do, it is very important that everyone in the team uses the same coding style. it is even important that in a company, all development teams use the same coding style so that code can be easily read and shared across teams and developers.
What coding style to use? I would say that this is mostly a matter of personal preferences as long as the style is constant and emphasizes the code structure.
I wrote my personal preferences in a document titled "ICS Coding Style". The name comes from the fact that I wrote it long time ago when a lot of peoples started to make changes to ICS. I wanted everyone to use the same coding style as me. Not an easy task because every developer think his coding style is the best.
The following image gives an idea of my coding style.

There are many "code formatter" on the market. The IDE is use (Delphi) has a fairly powerful code formatter. But this is not enough. For example, no code formatter will be able to rename the variables, methods and other identifiers according to a naming convention. Nad properly naming identifiers is an essential part of the coding sytle.
Code formatter also doesn't handle all aligments. For example, when the code must be broken into several lines, the code formatter will mostly go to the next line with some indentation. i prefer to aligne arguments and this become problematic for the code formatter when arguments are themself function calls.
