Php 是否可以在表格中按列填写值？

是否可以按列方式用值填充表格。比如说

<?php
echo "<table>";
for ($j=0;$j<6;$j++)
{
echo "<tr>";
for ($i=0;$i<6;$i++)
{
echo "<td>".$j.$i."</td>";
}
echo "</tr>";
}
echo "</table>";
?>

但我想让桌子看起来像

00  10  20  30  40  50
01  11  21  31  41  51
02  12  22  32  42  52
03  13  23  33  43  53
04  14  24  34  44  54
05  15  25  35  45  55

我提出了一个条件，即不更改填充在表中的值。（将echo从$j.$i更改为$i.$j会带来这种外观，但我希望按列填充数据）。它是如何实现的？

甚至没有深入讨论JS问题的细节，您的PHP是完全错误的（如果查看PHP生成的HTML，您应该能够看到这一点）：

echo'
“.$i.
”

应该是这样的：

echo '<li value="'.$i.'" id="'.$i.'" onclick="loadXmlDoc(\''.$i.'\',\''.$variable.\''")>'.$i.'</li><br>';

echo'
”.$i.

'；

我认为：

$variable1="xyz";
for($i=1; $i<=$pages; $i++)
{   
    echo '<li value"'.$i.'" id="'.$i.'" onclick=loadXmlDoc("'.$i,$variable.'")>'.$i.'</li>';<br>
}

$variable1=“xyz”；
对于（$i=1；$i这是你真正的做法，老式风格，完整的评论以供解释
