Greetings, I encountered such a task, I recently started working with php, and this task caused me difficulties.

In general, there is a table, it is filled with numbers, if at least in one cell there is a number, then we leave a row. If the row is completely empty, then delete it altogether, that is, do not display this row in the table.

For clarity, the picture:

$cols = 7; $arr = [ ["1","2","3"], [], ]; echo '<table>'; foreach( $arr as $el ) { echo '<tr>'; if($el) { for($i = 0; $i < $cols; $i++) { if($el && $i < count($el)) { echo '<td>' . $el[$i] . '</td>'; }else { echo '<td></td>'; } } } echo '</tr>'; } echo '</table>';
