/* button styles */
.button0 { background-color: Orange ; border: 110; color: black; text-align: center; text-decoration: none; display: inline-block; border-color: #ff0000; }

这是由于表格中的 width:100%; 造成的。删除它工作得很好。
/* table-itemtable styles */
table { border-collapse: collapse;}
th, td { text-align: center; padding: 8px;}
th {background-color: #4CAF50; color: white;}
tr {border-bottom: 1px solid;}
tbody { display: block; }
tbody {
height: 500px; /* Just for the demo */
overflow-y: auto; /* Trigger vertical scroll */
overflow-x: hidden; /* Hide the horizontal scroll */
}<div id="tablediv">
<table cellspacing="0" id="itemtable" align="center">
<tr>
<th> SLno</th>
<th>Item name</th>
<th>Item code</th>
<th>Supplier</th>
<th>Received qty</th>
<th>Accepted qty</th>
<th>Rejected qty</th>
<th>Remarks</th>
</tr>
</table>
</div>编辑:
从 CSS 中的 div 中删除 float:left。这是导致问题的原因。而是使用 display:inline-block
关于javascript - 无法使用对齐参数将表格放置在中心，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42851161/
