Do you mean something like this? <?php // get the "name" headings that you need for the columns // and also use them as keys in a "template" array // $res = $db->query("SELECT DISTINCT name FROM dataset ORDER BY name "); $names = $res->fetchAll(); $heads = array_column($names, 'name'); $temp = array_fill_keys($heads, ''); $table_header = "<tr><td></td><td class='thead'>Result</td><td class='thead'>" . join("</td><td class='thead'>", $heads) . "</td></tr>\n"; // now get the data // store in an array by "id" // witd subarrays for each name $res = $db->query("SELECT id , edate , result , name , nos FROM maintab m JOIN dataset d ON m.id = d.mid ORDER BY id "); $data = []; foreach ($res as $r) { if (!isset($data[$r['id']])) { $data[$r['id']] = [ 'edate' => $r['edate'], 'result' => $r['result'], 'names' => $temp // the template array from earlier ]; } $data[$r['id']]['names'][$r['name']] = $r['nos']; // put value in tempate array } // now we simply output data array into html table rows $tdata = ''; foreach ($data as $row) { $tdata .= "<tr><td>{$row['edate']}</td><td>{$row['result']}</td><td>" . join('</td><td>', $row['names']) . "</td></tr>\n"; } ?> <html> <head> <title>Example</title> <style type='text/css'> td { padding: 4px 10px; } .thead { font-weight: 600; border-top: 1px solid gray; border-bottom: 1px solid gray; } </style> </head> <body> <table> <?= $table_header ?> <?= $tdata ?> </table> </body> </html> OUTPUT [edit] PS Sorry about the data typo. That's what happens when people post pictures instead of copyable text.
