I am doing a webpage using HTML and PHP. Below, I attach a picture of my problem.

My first problem is that I cannot give the format I want to the table:
- I'd like to adjust to the content columns 1, 2, 3 and 4.
- Column 5 (last column) should have the more space the better.
- The
aaaaaaaaaaaaaaaaof the last column should not go beyond the table. It should be split up or with a line break when reach the column end.
Here a piece of my code:
echo "<table><tr>";
echo '<td width="40">ID</th>';
echo '<td width="50">Organism</th>';
echo '<td width="50">Chromosome</th>';
echo '<td width="50">Gene name</th>';
echo '<td>Sequence</th>';
echo "</tr>";
while($row = mysqli_fetch_array($result2)) {
echo "<tr>";
echo "<td>$row[id_send]</td>";
echo "<td>$row[organism]</td>";
echo "<td>$row[chromosome]</td>";
echo "<td>$row[gene]<br></td>";
echo "<td>$row[sequence]</td>";
echo "</tr>";
}
echo "</table>";
