为什么添加行和列后，联系表格不起作用？

Question

由于某种原因，在添加了“组行”和“列”列后，我的表格无法正常工作。如果我删除所有样式，它将起作用，但看起来会丑陋。另外，表格表示该消息已成功发送，但我没有收到消息。如果我删除所有样式，它将起作用，我将收到消息。那就是裸体

<form method="POST">
<label for="name">Name: <input type="text" name="name" id="name"></label><br>
<label for="name2">Company name: <input type="text" name="name2" id="name2"></label><br>
<label for="email">Email address: <input type="email" name="email" id="email"></label><br>
<label for="mobile">Mobile number<input type="text" name="mobile" id="mobile" placeholder="Enter Mobile Number" class="form-control" pattern="\d*" required /></label>
<label for="address">Full address<textarea name="address" id="address"placeholder="Enter Address" class="form-control"></textarea></label>
<label for="message">Message: <textarea name="message" id="message" rows="8" cols="20"></textarea></label><br>
<label for="dept">Send query to department:</label>
<select name="dept" id="dept">
    <option value="sales">Sales</option>
    <option value="support" selected>Technical support</option>
</select><br>
<input type="submit" value="Send">
</form>

的裸体设置

Answer 1

因此，从技术上讲，我的问题是，我为标签和输入添加了关闭标签，例如＆lt; label for =“ Mobile”＆gt;移动号＆lt; input＆lt; input type =“ text” name =“移动” id =“移动” id =“移动”占位符= “输入手机号” class =“ form-control”模式=“ \ d*”必需/＆gt;＆lt;/label＆gt;，解决方案是以下
