 ### 3.7. Exceptions to the Formatting Rules For Better Readability
-There are some special situations where vertical alignment and longer lines does greatly aid readability, for example the initialization of some table-like multiple row structures. In these **rare** cases exceptions can be made to the formatting rules on vertical alignment, and the defined line length can be exceeded.

 To prevent the layout from being reformatted, tell `clang-format` to [disable formatting](https://clang.llvm.org/docs/ClangFormatStyleOptions.html#disabling-formatting-on-a-piece-of-code) on that section of code by surrounding it with the special comments `// clang-format off` and `// clang-format on`.

 The other code guidelines will still need to be applied within the delimited lines of code, but with `clang-format` off care will be needed to check these manually. Using vertical alignment means that sometimes the entire block of code may need to be realigned, good judgement should be used in each case with the objective of preserving readability yet minimising impact.

 This is to be used with discretion, marking large amounts of code to be left unformatted by `clang-format` without reasonable justification will be rejected.
