i代码如下:

<?php
header('Content-Type: text/html; charset=utf-8');


echo <<< 'INPUT'
<form>
请输入表格的行数:<input type="text" name="row">列:<input type="text" name="col">
<button>提交</button>
</form>
INPUT;

$row = $_GET['row'];  //获取行
$col = $_GET['col'];  //获取列
echo '<table border="1" cellspacing="0" cellpadding="5" width="70%" >';  //输出表格
for($i=0;$i<$row;$i++){
    echo '<tr>';
    for ($j=0;$j<$col;$j++){
        echo '<td></td>';
    }
    echo '</tr>';
}
echo '</table>';

echo '<caption style="font-weight: bolder;color: #9A0000; font-size: 24px;">九九乘法表</caption>';

for ($i=1;$i<=9;$i++){
    echo '<tr>';
    for ($j=1;$j<=$i;$j++){
        echo '<td style="border: 1px solid #5e5e5e">'.$j.'x'.$i.'='.($i*$j).'</td>';
