Question

我真的很沮丧..我真的需要正确显示这张表。如何将此代码设置为垂直显示表格，如下所示：

1 - 4 - 7

2 - 5 - 8

3 - 6 - 9

而不是这样：

1 - 2 - 3 - 4

5 - 6 - 7 - 8

9 - ...等等

试试这个。这是纯粹的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/>';

}

由于我无法知道你用来遍历它并生成表的原始数据结构，我把它假定为一维数组，你想把表打印为3列，如你所说，动作这里是一个PHP Fiddle - 命中运行来执行它 - 只要列为3，行就是动态的，这适用于任何数组长度

PHP： 已更新为命名目的

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://ajax.aspnetcdn.com/ajax/jquery.validate/1.14.0/jquery.validate.min.js"></script>
<form>
    value 1
    <input name="value1"
           data-rule-smaller_than="[name='value2']"
           data-msg-smaller_than="value 1 must be smaller than value 2" /><br/>
    value 2
    <input name="value2"
           data-rule-not_smaller_than="[name='value1']"
           data-msg-not_smaller_than="value 1 must be smaller than value 2"/><br/>
    <input type="submit"/>
</form>

修改现在，如果要更改列号，例如将其设置为5，则需要执行以下操作：

1st - 设置<?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; ?> 第二 - 添加更多变量来保存值，例如，*考虑它是5列：

$colNum = 5;

并且不要忘记增加乘数$x4 = isset( $dataArr[$i + 3 * $rowNum] ) ? $dataArr[$i + 3 * $rowNum] : '-'; $x5 = isset( $dataArr[$i + 4 * $rowNum] ) ? $dataArr[$i + 4 * $rowNum] : '-';

然后，对于您添加的每个额外列，您需要添加* $rowNum，如：

<td></td>

这是另一个显示上述5列的PHP Fiddle。
