【问题讨论】：

“添加分页”是什么意思？对不起，我是意大利人，我不明白：P 但如果你解释一下，也许我可以帮助你；）
我想将一次可以显示的行数限制为 20，然后当我单击下一个按钮时，其他行将替换当前视图中的行我不知道从哪里开始，所以我寻求帮助谢谢。
您的问题已经在这里得到解答的接缝：http://stackoverflow.com/questions/19605078/how-to-use-pagination-on-html-tables
这是最简单的方法。取 2 $var - 限制和偏移，初始化它们并从 URL 中读取它们。单击下一个或上一个按钮时，将值传递给 URL，页面将重新加载，从 url 读取限制和偏移量并运行新查询以获取更新的数据。您的查询应该类似于SELECT * FROM table LIMIT $offset,$limit

【解决方案1】：

如果你想为你的表格分页，你可以这样做：

<?php
 include ("Connection.php");
?>
<html>
<head>
<link rel="stylesheet" type="text/css" href="Design.css">

<script type=" text/javascript">
function deleteRecord(id) {
if(confirm("Are you sure you want to delete this record?")) {
window.location.replace("delete.php?id=" +id);
} 
} 
</script>

</head>
<body>
<table>
<th><center>ID</center> </th>
<th><center>Item Name</center> </th>
<th><center>Brand</center> </th>
<th><center>Initial Price</center> </th>
<th><center>Sales Price</center> </th>
<th><center>Quantity</center> </th>
<th><center>Dealer</center> </th>
<th><center>Edit</center> </th>
<th><center>Delete</center> </th>
<th><center>Add</center> </th>
<th><center>Minus</center> </th>
  <?php 
  $query = "SELECT * FROM tableinvplastic ORDER BY id DESC LIMIT 1";
  $stmt = $con->query($query);
  $data = $stmt->fetch(PDO::FETCH_ASSOC);
  $num_rows = $data['id'] / 20;
<?php
function get_result(index,initial,limit)
{
   $qry = $con->prepare("SELECT * FROM tableinvplastic LIMIT $initial,$limit");
   $qry -> execute();
   if($qry->rowCount() > 0)
   {
      return $rows;
   }
else return  'empty';
}
?>
<?php
     for($i=0;$i<$num_rows;$i++)
{
 if($i = 0) 
{
$limit = 0;
$initial = 20;
}
else 
{
$initial = ($i*20+1)
limit = $i*20*2);
}
$rows = get_result($i,$initial,$limit);
print "<tr>";
    print "<td>" .$row['ID']. "</td>";
    print "<td>" .$row['ItemName']. "</td>";
    print "<td>" .$row['Brand']. "</td>";
    print "<td>" .$row['InitialPrice']. "</td>";
    print "<td>" .$row['SalesPrice']. "</td>";
    print "<td>" .$row["Quantity"]. "</td>";
    print "<td>" .$row["Dealer"]. "</td>";
    print "<td><a href='UpdatePlastic.php?id=" .$row["ID"]. "'>Edit</a></td>";
    print "<td><a href='#!' onclick = 'deleteRecord(" .$row["ID"]. ");'>Delete</a></td>";
    print "<td><a href='Add.php?id=" .$row["ID"]. "'>Add</a></td>";
    print "<td><a href='Minus.php?id=" .$row["ID"]. "'>Minus</a></td>";
    print "</tr>";
}

</table>

<style>
table {
width:60%;
position : absolute;
top : 200px;
left : 100px;
}
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th {
padding: 5px;
text-align: left;
background-color: #4CAF50;
}
</style>
</body>
</html>

这样的东西应该可以工作...对不起，我现在没有本地服务器。
