这是由于表中的width:100%;。因此它可以正常工作。

/* 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 */

编辑:

从CSS中的float:left移除div。这会导致问题。请勿使用display:inline-block

删除宽度:100%;从表格开始,它将与中心对齐。

只需添加text-align:center; CSS中的th和td。

&#13;
&#13;
/* table-itemtable styles */
table { border-collapse: collapse; width: 100%;}
th, td { text-align: left; padding: 8px; text-align:center;}
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 */
}
&#13;
<div id="tablediv">
<table cellspacing="0" id="itemtable"> 
    <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>
