有人能解释一下 input 这怎么可能吗？类型为“submit”的虽然在第三个 <tr> 内，但位于左上角
我可以通过 margin 将其位置更改为正确的位置和 position属性，但在这种情况下根本不需要它们。
看代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<div style="border:2px solid black;margin-top:10%;">
<div class="row">
<table style="margin-left:10%;width:85%;" class="table table-hover">
<thead>
<tr>
<th>album name</th>
<th>Number of images</th>
<th>Order</th>
</tr>
</thead>
<tr>
<td>
<input placeholder="album's name" name="album_name">
</td>
<td>
<input placeholder="#of images eg.8" id="no_of_images" name="NoOfImages">
</td>
<td>
<input placeholder="order between other albums eg. 1" name="album_order">
</td>
</tr>
<tr>
<input style="" class="btn btn-info btn-md" value="Submit" name="submit">
</tr>
</table>
<table style="margin-top:10%;" id="images_table" class="table table-hover">
</table>
</div>

</html>最佳答案
像这样插入 td:
<td> <---------------
<input style="" class="btn btn-info btn-md" value="Submit" name="submit">
</td> <--------------
