"Nice" html table using SQL results - php

Question

I currently have this html table using SQL results to fill it:
<table>
<table border="1">
<tr>
<th>Username</th>
<th>holid</th>
<th>Start date</th>
<th>end date</th>
<th>Work days off</th>
</tr>
<?php foreach($rows as $row): ?>
<table border="1">
<tr>
<td><?php echo htmlentities($row['username'], ENT_QUOTES, 'UTF-8');?></td>
<td><?php echo htmlentities($row['starthol'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlentities($row['endhol'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlentities($row['days'], ENT_QUOTES, 'UTF-8'); ?></td>
<td>Approve</td>
<td>Reject</td>
</tr>
<?php endforeach; ?>
</table>
This works fine and everything, but the table is very messy and the headings are out of line. Is there a simple way to make this cleaner (php beginner).

Answer 1

Here is the extra table tag removed coding and see below for the css coding.
<table border="1">
<tr>
<th>Username</th>
<th>holid</th>
<th>Start date</th>
<th>end date</th>
<th>Work days off</th>
</tr>
<?php foreach($rows as $row): ?>
<tr>
<td><?php echo htmlentities($row['username'], ENT_QUOTES, 'UTF-8');?></td>
<td><?php echo htmlentities($row['starthol'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlentities($row['endhol'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlentities($row['days'], ENT_QUOTES, 'UTF-8'); ?></td>
<td>Approve</td>
<td>Reject</td>
</tr>
<?php endforeach; ?>
</table>
/*css styles*/
table {
border-collapse: collapse;
}
/* Zebra striping */
tr:nth-of-type(odd) {
background: #eee;
}
th {
background: #333;
color: white;
font-weight: bold;
}
td, th {
padding: 6px;
border: 1px solid #ccc;
text-align: left;
}

Answer 2

Delete the second <table border="1">, the one below the foreach instruction.
EDIT: And one of the first ones as well. Every <table> tag should have one corresponding </table> (that goes for all tags in HTML!)
Also, try to match <th>s with <td>s. Right now there are 5 <th>s and each row has 6 <td>s.
