I don't think this should be too hard, sure it would be a cinch for you guys. 
There are two columns, Column A, and Column J.
<colgroup><col><col></colgroup><tbody>
</tbody>
If J2=A2, then delete the corresponding cell in A2.
If J3=A3, then delete the corresponding cell in A3.
And so on and so forth.
So the result after the macro would be:
<colgroup><col><col></colgroup><tbody>
</tbody>
That's pretty much it!
