我有一个可编辑的网格，我想在其中编辑 CSS，以便 textarea 显示最大宽度，但不知何故我无法增加文本区域的宽度。
我的数据库有三列：
- ID
- 姓名
- 闲话
我正在检索所有内容并将其显示在使用 PHP 的可编辑网格中。
index.php 代码
<?php
$db = new mysqli('localhost', 'root', '', 'bollywood');
$db->set_charset('utf8');
if ($db->connect_errno) {
die('Check the database connection again!');
}
$userQuery = 'SELECT Id,Name,Gossip FROM bollywood';
$stmt = $db->query($userQuery);
?>
