我真的很沮丧。。我真的需要把这张桌子展示一下。我如何设置此代码以垂直显示表格，如下所示：
1-4-7
2-5-8
3-6-9
不是这样的：
1-2-3-4
5-6-7-8
9-。。。ect
<?php
$PNG_WEB_DIR = plugin_dir_path( __FILE__ ).'temp/';
wp_mkdir_p($PNG_WEB_DIR);
$cols = $this->settings['cols'];
$rows = $this->settings['rows'];
$label_number = 0;
// die($_GET['order_ids']);
$order_ids = explode(',',$_GET['ids']);
$order_count = count($order_ids);
$labels_per_page = $cols*$rows;
$page_count = ceil(($order_count)/$labels_per_page);
for ($page=0; $page < $page_count; $page++) {
echo '<table class="address-labels" width="100%" height="100%" border="0" cellpadding="0">';
$last_height = 0;
$current_height = $current_width = 0;
$current_row = 0;

由于我不知道你用来循环并生成表的原始数据结构，我假设它是一维数组，并且你想像你所说的那样将表打印为3列，看看这里有一个PHP Fiddle-点击运行来执行它-这将适用于任何数组长度，只要列是3，行是动态
PHP: 为命名目的更新
<?php
$table = '<table class="address-labels" width="30%" border="0" cellpadding="0">';
$dataArr = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16, 17);
$colNum = 3;
$rowNum = ceil(count($dataArr)/$colNum);
for($i=0; $i < $rowNum; $i++){
$x1 = isset( $dataArr[$i] ) ? $dataArr[$i] : '-';
$x2 = isset( $dataArr[$i + $rowNum] ) ? $dataArr[$i + $rowNum] : '-';
$x3 = isset( $dataArr[$i + 2 * $rowNum] ) ? $dataArr[$i + 2 * $rowNum] : '-';
$table .= '<tr><td>' . $x1 . '</td><td>' . $x2 . '</td><td>' . $x3 . '</td></tr>';
}
$table .= '</table>';
echo $table;
?>
编辑：现在，如果您想更改列编号，例如将其设置为5，则需要执行以下操作：
第一套$colNum = 5;第二-添加更多变量来保存值，如*，考虑到它是5列：
$x4 = isset( $dataArr[$i + 3 * $rowNum] ) ? $dataArr[$i + 3 * $rowNum] : '-';
$x5 = isset( $dataArr[$i + 4 * $rowNum] ) ? $dataArr[$i + 4 * $rowNum] : '-';
别忘了增加乘数* $rowNum
然后，对于您添加的每一个额外列，您都需要添加<td></td>，如：
'<td>' . $x4 . '</td><td>' . '</td><td>' . $x5 . '</td><td>' . '</td>'
下面是另一个PHP Fiddle，显示了上面5列的内容。
试试这个。它是纯php
<?php
$cols = 3;
$data = range(1,29);
// classic
$index = 1;
foreach($data as $el)
{
echo $el.' '; if ($index % $cols ==0) echo '<br/>';
$index++;
}
echo '<br/><br/>';
// special
$rows = $cols ;
$cols = floor(count($data)/$cols);
for($row = 0 ; $row < $rows; $row++){
for ($index = $row; $index < count($data); $index += $rows)
echo $data[$index].' ';
echo '<br/>';
}
