$iqry->execute(); 

$iqry->bind_result($code,$quantity,$item,$unit); 
$iqry->store_result(); 

while ($iqry->fetch()){ 
    $result[] = array("code"  => $code, 
        "quantity" => $quantity, 
        "itemname" => $item,

    echo "<td>" .$r['itemname']. "</td>";

試試這個

$iqry = $mysqli->prepare("SELECT `table_inventory`.code, `table_inventory`.quantity, `table_item`.itemname, `table_item`.unitmeasure 
        FROM `table_inventory ` LEFT JOIN `table_item` ON table_inventory.id=table_item.id order by `table_inventory`.id"); 

願這幫助你。
