How to disallow CKeditor to 'FIX' my HTML code ?

Actually, CKeditor is loading a HTML code from database having the following code :

<table>
<tbody>
<tr>
<td>A</td>
<td>B</td>
<td>C</td>
<td>D</td>
</tr>
<tr>
<td>Hours</td>
<td>[numeric_35]</td>
<td>[numeric_34]</td>
<td>[formula_193]</td>
</tr>
[formula_196] <!-- This will output <tr> <td>1</td> <td>2</td> <td>3</td> </tr> --> </tbody>
</table>

If loads it as follow :

[formula_196] <!-- This will output <tr> <td>1</td> <td>2</td> <td>3</td> </tr> -->
<table>
<tbody>
<tr>
<td>A</td>
<td>B</td>
<td>C</td>
<td>D</td>
</tr>
<tr>
<td>Hours</td>
<td>[numeric_35]</td>
<td>[numeric_34]</td>
<td>[formula_193]</td>
</tr>
</tbody>
</table>

Is it possible to tell CKeditor stop placing my line containing "[formula_196] <!-- This will output <tr> <td>1</td> <td>2</td> <td>3</td> </tr> -->" at the beggining of the HTML code ?
