这是我的表格，当我垂直添加新项目列表但我希望数组项目水平示例[item1，item2，item3，item4]之后，数组4项水平只创建另一个td然后再次水平数组4次

必填项：

{1,2,3,4}
{5,6,7,8}

从左到右的数组

else数组垂直{1,5} {2,6}，{3,7]，[4,8]

尝试以这种方式更改表格

<table class="box1" width="700" border="1">

<?php 
        $cnt= 0;
        $nThumbXRow =5 ;
        $sql = ("SELECT * FROM bookstore");
        $result = mysql_query($sql);
        while($row =mysql_fetch_array($result)){
            if ($cnt%$nThumbXRow == 0){
                echo "<tr>";
            }
             echo "<td><img src='" . $row['image'] . 
                   "' height='250' width='150'><br />" .  
                   $row['bookname'] ."<br />" .  
                    $row['author'] . 
                    " <br /><input type='submit' name='add'
                        value='Add Cart'></td>";
            $cnt++;
            if ($cnt%$nThumbXRow == 0){
                echo "</tr><!-- row ending here -->";
            }

        }
    ?>     
</table>

用于测试echo尝试这样一个简单的情况（只有按钮）

echo "<td><input type='submit' name='add'
                    value='Add Cart'></td>";

在这个示例中（我没有你对你的IMG进行db，所以我用字符串值更改了var值，你可以在第一行中看到2行pic 4，在第二行中看到2行。

然后，如果您没有获得相同的结果，那么您的选择或价值可能会有问题。

<table class="box1" width="700" border="1">

<?php 

    $cnt= 0;
    $nThumbXRow =4 ;
    $book = 0;
/*    $sql = ("SELECT * FROM bookstore");
    $result = mysql_query($sql);
    while($row =mysql_fetch_array($result)){*/
    while( $book<=5 ){
        if ($cnt%$nThumbXRow == 0){
            echo "<tr>";
        }
/*         echo "<td><img src='" . $row['image'] . 
               "' height='250' width='150'><br />" .  
               $row['bookname'] ."<br />" .  
                $row['author'] . 
                " <br /><input type='submit' name='add'
                    value='Add Cart'></td>";*/
            echo  "<td><img src='" . "row['image']" . 
               "' height='250' width='150'><br />" ."row['bookname']<br />" .  "row['author']<br />" .  "<input type='submit' name='add'
                    value='Add Cart'></td>";
        $cnt++;

        if ($cnt%$nThumbXRow == 0){
            echo "</tr><!-- row ending here -->";
         }
        $book++;

      }
?>     
</table>
