Insert spaces when tab key is pressed

[fxha]

PR #119 disabled tab focus, but does not insert a tab/spaces into document because if you insert a tab or multiple spaces, it will get converted into one space. So we have to find a way to resolve the problem.

Maybe use something like this:

<span class="cm-tab" role="presentation" cm-text="	">  </span>

Code template

if you insert a tab or multiple spaces, it will get converted into one space.

Do you find the reason why it will convert multiple spaces to one space? I think this is the key point to this issue.

I find a question on stack overflow https://stackoverflow.com/questions/433493/why-does-html-require-that-multiple-spaces-show-up-as-a-single-space-in-the-brow

@fxha i have fixed the problem bellow:

if you insert a tab or multiple spaces, it will get converted into one space.

Do you want to continue your work, Code template ?

I think somewhere in marked.js, importMarkdown or exportMarkdown because a b is also converted to a b - maybe a markdown rule?

@Jocs And how do you solve it?

  display: block;
+  white-space: pre-wrap;
