This solution makes a few assumptions that may not be valid. It assumes
that none of the <td> tags will contain nested tags; that none of the <td>
tags will be empty; and that there will be no space between the <tr> and
the first <td>.
Here's an updated version of the regex.
Find
(<tr[^>]*>\s*(?:<td[^>]*>(?:(?!</td>).)*</td>\s*){2})<td[^>]*>(?:(?!</td>).)*</td>
Replace
\1
The key here is the (?:(?!</td>).)*, which will check to see if the next
thing in the string is </td>, and if it's not, it will match one character,
then repeat that, matching one character at a time, until it gets to the
</td>.
