In your loop, check if it should add a tr beginning or end.

This is just a sample code:

<?php $sql = "select * from study";
$rs = mysql_query($sql);
$i = 0;
echo "<table>";
while($row = mysql_fetch_array($rs)){
    if($i%3 == 0) echo "<tr>";
    echo "<td><input type="checkbox">$row[studyname]</td>";
    if($i%3 == 2) echo "</tr>";
    $i ++;
}
echo "</table>";

Actually, if you use div it will be very easy.
