How do I disable this for my post?

Answer 1

This is due to jtab which will be active in code blocks use <pre></pre> to delineate your code blocks to fix it like so:

<pre>
          C | G
        F   |   D
      B♭    |     A
      E♭    |     E
        A♭  |   B
          D♭| G♭
</pre>

...which produces:

          C | G
        F   |   D
      B♭    |     A
      E♭    |     E
        A♭  |   B
          D♭| G♭
