If the text inserted into a Code Macro in Confluence is too long, Confluence will wrap it to a new line.

ソリューション

1.  Navigate to the Stylesheet screen in Confluence Admin (at Browse >> Confluence Admin >> Stylesheet)

2. Add the following CSS:

   code { /* forces the text not to wrap */  
       white-space: nowrap !important;  
   }

3. Click Save

4. Navigate to the page containing the wrapped code block. It should now be unwrapped.
