Question

我有一个表生成一个循环，其中列标题通过fri和时间数组以30分钟为间隔24小时我刚刚缩短了示例代码：

$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>

现在我的代码可以很好地生成带有rowspan的表，但我知道我必须在下一行中删除必要的td，这取决于我的rowspan（$ res）包含多少行。这可能是我从公共汽车上摔下来的部分:) 我在这里想要实现的是获取行号和“td”。隐藏在

后面的行中

// 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";
 }
}

我甚至不确定我是否在正确的问题上接近整个概念，我们将非常感谢任何帮助。谢谢!!

在一天结束时，我的表应如下所示：

这是您的填写答案

好吧，我没有时间来制作一个完整的阵列，但希望它对你有用。
