動態錶行跨度

Question

我有帶列標題的循環產生的表紋槽用30分鐘的時間間隔週五，時間序列爲24小時我剛纔縮短示例代碼：

$times = array(00:00, 00:30, 01:00, 01:30); 
$skip = array(); 
$row = 1; 
<table> 
<tr> 
    <td>Time</td><td>Mon</td><td>tue</td> 
<tr> 
foreach($times AS $val){ 
    $stmt = $mysqli->prepare(" 
    SELECT `show`,`time_start`,`time_stop`,`show_day` 
    FROM `db_shows` WHERE `time_start`='$val' 
    "); 
    $stmt->execute(); 
    $stmt->store_result(); 
    $stmt->bind_result($myrow[show],$myrow[time_start],$myrow[time_stop],$myrow[show_day]); 
    $stmt->fetch(); 
    // GET THE ROWSPAN 
    $a = new DateTime($myrow[time_start]); 
    $b = new DateTime($myrow[time_stop]); 
    $interval = $a->diff($b); 
    $res = $interval->format('%h'); 
    $res *= 2; 
    $res += 1; 
    // ARRY FOR ROWS TO SKIP TD 
    code in second part 
    // APPLAY DISPLAY NONE IF NEEDED 
    code in second part 
    // BUILD COLUMNS 
    switch($myrow[show_day]){ 
    case "":$tds = "<td>&nbsp;</td><td>&nbsp;</td>"; break; 
    case "mon":$tds = "<td rowspan="$res" style="$mon">$myrow[show]</td><td>&nbsp;</td>"; break; 
    case "tue":$tds = "<td>&nbsp;</td><td rowspan="$res" style="$tue">$myrow[show]</td>"; break; 
    } 
    <tr> 
    <td>$val</td>$tds 
    </tr> 
$row++; 
}  
</table> 

現在我的代碼工作正常使用rowspan生成表，但我知道必須根據行rowspan（$ res）包含多少行來刪除下一行中必需的td。這可能是我跌倒出車的一部分:) 我試圖在這裏實現是獲得行號和「日TD」在隨後

// ARRY FOR ROWS TO SKIP TD 
if($res >=2){ 
$rowCount = $res -1; 
$rowSkip = $row; 
for($i=1;$i <= $rowCount; $i++){ 
$rowSkip++; 
$skip[$rowSkip] = $myrow[show_day]; 
} 
} 
// LOOK IF ROW HAVE VALUE 
foreach($skip AS $key2 => $val2){ 
if($row == "$key2" && $myrow[show_day]="$val2"){ 
    $$val2 = "display:none"; 
} 
} 

我行隱藏我甚至不確定我是否正在接觸關於正確問題的整個概念，任何幫助都將不勝感激。 謝謝！

在一天結束的時候我的表應該是這樣的：

table

這是個夠答案

嗯，我沒有好時機，蛋糕的全陣列，但希望它會爲你工作。
