Your question is dealing with a results page. A results page is not necessarily intended to show the entire data in the record, that is the job of the details page.
I would take Willi's solution a step further and display ellipses if the mail address is to long:
<?php echo substr(($row_YourRecordset['your_db_column']),0,10); ?><?php if(strlen($row_YourRecordset['your_db_column']) > 10) echo "... "; ?>
Willi's solution may not be the answer you where hoping for, but in reality it is the best solution to the problem.
other options would be to add a width and overflow style to the table cell to add vertical scroll bars if the content where to wide for the cell, in my opinion, this looks worse than cutting it off.
The repeating table behavior will allow you to use different styles for evan and odd rows. See the "Using Repeating Tables in Data Bridge" tutorial on the Data Bridge support page:
