I output data from atabase in table.
In result table created with next code:
while($i=$res2->fetch_assoc()) {
$a++;
$t2.='
<tr>
<td>'.$a.'</td>
<td>'.date_format(new DateTime($i['date']),'d.m.Y').'</td>
';
if($valid!='id'){
$t2.='
<td>'.$partner.'</td>
';
}
$t2.='
<td>'.$http_referer.'</td>
</tr>';
}
$t1='
<table class="table table-hover table-bordered">
<thead>
<tr>
<th class="column_th_number">№</th>
<th>Date</th>
';
if($valid!='id'){
$t1.='
<th>Partner</th>
';
}
$t1.='
<th></th>
</tr>
<tr>
<td colspane="2">
</td>
</tr>
</thead>
<tbody>
';
$t3='
</tbody>
</table>
';
echo $t1.$t2.$t3;
but in the result I see that last row was not closed (see image):

Tell me please why last row was not closed?
And how can I make this right?
Thanks ALL.
Error was with colspan(value does not match the number of columns).
Thanks all for help
