Table html coding being stripped off

For some reason the html coding related to tables is being stripped off the image information

For example on the page above, when the following is entered:

<table><tbody>
<tr><td>w#cc0</td><td>w#cd0</td></tr>
<tr><td>w#cc1</td><td>w#cd1</td></tr>
<tr><td>w#cc2</td><td>w#cd2</td></tr>
<tr><td>w#cc3</td><td>w#cd3</td></tr>
</tbody></table>

It reduces it to:

w#cc0w#cd0 w#cc1w#cd1 w#cc2w#cd2 w#cc3w#cd3

Can this be fixed? Was this a result of a recent plugin update? and if so, what version should i revert to to stop this from happening
